Kreink-I feel so awful for you! But do not feel bad talking about poo, this is a place that will not judge you, we all have bowel issues! When I was on 3600 mg. gabapentin,I was still as constipated as before I began taking it, I just can not see that as the problem, but I am not a doctor. Due to the opiates,etc., that I take, I was constipated all of the time, for 2-3 weeks at a time, which is dangerous.I read about xenical one day, saw the side effects included loose stools, got excited, doctor let me try it, works like a charm, as long as i take it with abit of fat.Go and get checked, you do not need to live like this!
