I'm also semi-convinced that I might be addicted to my pain meds... the only way I get a good nights sleep is if I take half a dose of my pain med. Seriously- knocks me out and I sleep great. I started freaking out about it the other night so I lessened the dose- which was fine. And the next night I tried not to take it- and I could not sleep. I get anxious thinking about going to sleep without this drug.
I seriously have a phobia of becoming addicted to drugs... I've always been this way, so my fear is nothing new. But I just wanted to share.
