I know just how you feel Faylowell, I try not to think about it too often but each day I am so limited in what I can do, where I can go - and then waste so much of the day with all the exhausting preparations and precautions..
Whats meds are you currently taking? I had some fairly rapid weight gain on anafranil thinking back, even though I was exercising more than usual at that stage if anything. Haven't experienced it so much with other meds though. I rarely take anything these days because like you, they just destroy my sleep pattern. Long term insomnia is bad enough by itself (Especially when the kids need to get to school first thing in the morning), but being awake during those pre-dawn hours without any sounds or distractions just seems to heighten paranoia and allow more time to focus on it, well at least for me.
Hope your able to work through those side effects and find a way to put to your mind at ease..
