Ouch, yes, shift work can truly mess with your sleep and health! Actually, the boyfriend of my therapist has been a DJ for many years, and she told me he has needed three full years under *her professional guidance!* to get back to a natural sleep pattern, so that tells me something about how hard that is to do when it's been that disrupted for a long while.

My sleep patterns were more subtly disrupted, staying up late (until 2 AM), getting tired even later (at 3 AM), and only sleeping around 3:30 if I was lucky. (If not I would be awake frustrated because I knew I wouldn't be able to function normally the next day - of course not helping my sleep because I was angry :D)

Anyway. Glad you're experiencing more and more good nights of sleep - it's a magical feeling, only the once sleep deprived can know :D
