brief rundown of my medical history - no problems until 4 years ago started having urgent morning diahorrea (ok for rest of day) and nausea... various tests (barium enema, sigmoidoscopy, endoscopy) all came back clear so diagnosed with functional bowel problem. Just recently I have kept a food diary for my gp and having repeated my coeliac screening he agrees with consultants diagnoses as all bloods etc clear. He has given me imipramine to take to help the diahorrea. Since taking it last week I have noticed extreme fatigue during day, lightheadedness, although these were all symptoms I suffered with my IBS (fatigue, dizzy head, low blood pressure). I was wondering if I continued on the tablets if symptoms would go away as my body gets used to the medication. I would just love to get up in the morning and be full of buzz and energy the way I used to be - instead all I want to do is crawl back into my bed (im 43 btw). Any advice would be appreciated.
