I am a 47 year old male and for the past 2 years i've been having a lot of trouble moving the bowles. I went to my doctor and he did all the nescessary tests. The results were a small hiatal hernia, acid reflux and a slightly abnormal gastro. emptying test result. I'm taking the meds. my doc. prescribed and they've helped a little. I also need to mention that i've been on the methadone program for 10years and been clean since. The methadone never gave me a problem but for some reason for the past year, off and on i get severe stomach spasms, tightness in my neck and feel lousy about 2 hours after taking it. I also had hepatitis B 20 years ago but all my liver functions are normal. Why am i having this problem with the methadone? I've never been allergic to anything and i've had all different forms of this medication including the red liquid,which i'm on now. I hope i gave enough info. and did'nt overwhelm you. I would appreciate any feedback you have, if any. %-)
