dan, I am no expert!! but as a recovering addict I can only go by what I felt!!! I have withdrew from
percocet so many times I cant remember but on weeks that I tried before I got worse which is close to the dose you are taking now (four a day for two weeks)I still withdrew for a couple of days, and always ended up going back.
Since you have been on for so long you may begin to feel symptoms within 12 hours. Mine was an achy stomach and flu like symptoms for a couple of days and I began to feel better. If you make it three days dont go back!!!! Get sleep now I cant stress that enough also drink plenty of water and painkiller addiction thread is definitly the place to post for support.
