I was having difficulty sleeping before the meds anyway, so i don't think it is a side effect of them for me, more a symptom of the illness. i can now sleep okish. i can still wake up ear;ly, but when i did that before there was no getting back to sleep, now i can. i can still struggle to feel even remotely tired in the night time, and on those days I have taken a sleeping tablet. but it is a vast improvement. i'm not needing them every night and can sleep. it makes a lot of difference. and yea i feel like i am doing really well now, and it's actually a bit of surprise considering i was so low such a short space of time ago!
