I have done OxyContin for 14 months (150 + mg/day) and recently went to thailand for 3 weeks for vacation. I took subs with me expecting to wd but never did, I felt fine so I never took them. When I got back I started using again. Long story short, my lower left abdomen has kinda been bothering me. Thinking Im probably constipated, I stopped for a few days again recently.. honestly, just so I could take some good poops lol. Has anyone else experienced this? No withdrawls after long term use? I'm kinda shocked
