Yes
I have felt many creative blocks
So 
I exercise when I get like this
I drink more fluids and take 
vitamins
My brain fog gets a little better
Coffee and Tea help Me

When I was in college I experienced creative block all the time. I think it was mostly because I was restricted in what I could write about. When I experience it these days (which I still do, just not as often), I tend to associate it with feeling pressure from an audience. I have the same thoughts: What do people want to read? Who is going to like this? It's challenging to shake, I know. But to truly be free, I believe we need write for ourselves. That's where the passion shines through, and passion is attractive. If people read it, great. If they don't, you can still be proud of your work and not feel like you've wasted your time.

I have the complete opposite issue. I have so many ideas for different posts but haven't been able to execute any of them yet. I find I keep trying to complete one then a new idea comes and I start that. Time is my issue , coupled with the fact I have never blogged before so what might take someone 2-4 hours will take me 2-4 days,lol. I also seem to have some fear of my posts not succeeding, and maybe putting a little too much effort to achieve perfection. I don't mean fail in a monetary sense, I​ mean in general. Anyway, as long as I am learning every day and happy that what counts. 

I think a creative block is more about the little narrator in your head being too busy with noise from the universe and not enough mindfulness in the equation.

Caught my attention when you show a Steemit sticker on the laptop and Github :)

Creative block? Have sex!!

Wow @jamtaylor I absolutely get where you're coming from.

My first few weeks here I became so obsessed trying to post too many times a day, staying on here for crazy hours.

Now I am paying the price i am so sick and run down from the hours I have been putting in here that I really couldn't keep going I stopped posting for days at a time.

Since then (whilst I am still really sick) I have come back with a more focussed mindset, I have always been committed to writing my story and I never before expected to be paid for it - it was something I wanted to do for me.

Steemit made it possible I never would have put my work out there like this if it wasn't for this platform, I have cut back on quantity and I am now solely focussed on quality.

Good luck and I hope you enjoy your weekend away to recharge your creative energies - sometimes we just need to experience something new to get reinspired!

maybe this might help;

A lot of times we get writers block because we stay inside a creative box. I've found that if you step outside your comfort zone, that will hopefully spark a new creative hunger. And for those people who are stuck on "What" to write about, view my post on writers block: https://steemit.com/writersblock/@steemit-life/stuck-on-what-to-write-about-let-me-help

"I’ve felt stumped. This is because I’m getting caught up on maximising rewards and not about being authentic and sharing from my experiences." You are not alone. 
I write because I have the disease of writing, not because of the rewards attached to it. But I related to many of your points because I also feel this new kind of self-consciousness that I am not used to. Basically, I have been writing and creating images/art for many years and receiving limited economic rewards for it. And I certainly never ended up in a parody comic or a video because of my writing. The attention for writing and doing well on Steemit was not a motivating factor for writing on Steemit.  I write and create art because I am not really cut out for anything else. I get bored with most jobs if it includes any sort of routine. Additionally, I cherish my autonomy more than anything else (well, curiosity is right up there too). But I am beginning to feel that my authentic, honest voice, is not something that powerful people enjoy. This is the case inside of all power structures. I feel like a small person, always have.
Today I have been studying behavior modification theory and more specifically how monetary rewards do not actually bring about satisfaction and long-term instrinsic behaviors. Your post illustrates well why writers and artists are motivated from within and generally do not do well when the rewards are extrinsic in nature. 
I think I am motivated by the feeling that "I could lose it all." I exist on the fringes of the world, and I enjoy the beginnings of anything.

It's odd, because a lot of people, if they were in my shoes might do everything in their power to protect their investment. But you see, I never intended to become invested here. It happened as a by-product of me being an insanely driven writer. I am not different from the first day, except now i have a big investment, that was created by others rewarding me. I now experience conflict when I decide to post because of this thought process: What will the whales think of my post if I decide to tell the truth about things as I truly see them?
I never had that conflict in the beginning, and I see that I must just continue to write in the way i have always done: with total abandon. Doing otherwise will result in sub-par results that will not do anyone any good. Write for thyself! You are correct.
