When I got clean it took me 3 months to start sleeping normally. That was using absolutely nothing other than coffee and cigarettes.
Now I find myself in a similar situation again. I just can't wait that long now , work, family and such, that i am never able to get past 3 days it seems and I just cave in because it is easier than torturing myself for 3 months. last time I had a lot less responsibility.
I was thinking today that I bet almost everyone's body chemistry would go back to normal if they were only able to hack it out long enough.
