Topamax and severe abdominal pain

I've been on Topamax for over a year for hormonal migraines, and it's working great for the headaches. I started out at 25mg twice a day and now I'm up to 100mg twice a day. I've lost 40lb (mostly due to the drug -- but my appetite is starting to come back) and have just recently started experiencing the anxiety and tingling in the extremities. I've always felt I've had trouble concentrating and "finding the word", but I attributed it to lack of sleep because I have two small children. My most recent side effect, however, is most worrisome, which is the reason for my visit to this website. I am experiencing severe abdominal pain, almost constant, and it seems to be increasing. I had abdominal pain and diarrhea when I first started Topamax last year, but it stopped after the first month or so. I'm just wondering if maybe long term use can cause ulcers or other stomach problems. Anyone have any experience with this? I know from experience that Topamax dosages have to gradually weaned up and down, so I'm considering decreasing my dosage to see if my stomach problems will stop. I'm just in so much pain, yet my migraines have almost stopped now with 200mg a day, that I'm reluctant to change my dose.

I have been on Topomax for 2 years now at 200 mg. for mood stabilization. I was recently hospitalized for my depression and they upped my Topomax dose to 400mg saying it was the "therapeutic dosage". I went into the hospital weighing 116 pounds and I am 5' 6" tall. I started having diarrhea within a couple days. By the tiime I left 2 weeks later I had gone from a size 4 to a size 2. A month and 1/2 later I had lost 15 pounds, had severe abdominal pain everytime I ate, diarrhea every morning, nausea, and had absolutely no appetite.

My psychiatrist insisted it was not the medication and I went to a gastroenterologist for the full workup- ultrosound, colonoscopy, endoscopy and surprise surprise they found nothing. My Gastro doctor concluded it must be the meds so I started backing down on the Topomax and already the diarrhea has stopped. I am at 250 and up to 101 pounds now. I am taking in over 1200 calories a day but I still can't seem to gain weight. My doctor still doesn't believe it's the Topomax but it all points in that direction. Instead they insist I'm just not eating enough But I make sure to force myself to get down 3 meals plus 2 ensures and some snacks. I still am waiting to get some appetite back. I know some women would love to be in my place to have to try to gain weight but I feel like I'm dying all the time. I have no energy, I can't even get up in the morning to take care of my kids. My fiance left me because he got so fed up with my "sickness" and thought it was all in my head. I have my mother living with me now just to help me take care of my own children and it breaks my heart that I don't have the enery to play with them. I can't see my psychiatrist for 2 more weeks so I am taking my level of medication into my own hands which I know you are not supposed to do but at this point it's that or lie in bed feeling like I'm just wasting away.
