constipation, drug induced
"I have been on a small amount of Methadone 5mg twice daily.  I can only go to the bathroom like 1 -2 times a week and then it's little hard balls.  I took Movantik 25mg 1 time and went within 1 hour that would have been ok, but then a few minutes later my stomach hurt I mean realty hurt I was in tears then I went again, well I have gone so much it is pure water now and I will not take this again, I would be scared to try the 12.5mg.  No withdrawal symptoms but the runs well the last time I had this that bad my kidneys were shutting down, so I fear for this, cannot eat or drink anything it runs right through me...be careful, I would try the lower amount first and see how that goes."
