I stopped taking my Subs about 18 days ago. Was down to 1mg am and 1mg pm. Was having a lot of severe back pain, so last week I went to my Doc and he gave me 100 Perc 10's and said to take 1 every 6 hrs for 50 of them, then start taking 1/2 a pill for the rest and I should be fine. Now I know all about the addiction and believe me, I'm not going there again. Plus I almost had to do 60 yrs in prison so that was enough to scare the crap out of me. Anyway, what I'm getting at is as soon as I get near that six hr mark my WD or backpain and RLS. returns. Now since I can feel the Perco, shouldn't that mean the Sub is out of my system or am I just thinking this is happening and it's not. I doubt this would be WD from Perco since I don't think I've taken enough plus it's been happening all along. BTW, I have been on the Percs exactly one week today and still have 80 so as you can see, I'm not abusing them b/c when I did abuse Lortab, that many would be gone already!!
