Irritable Bowel Syndrome
"I&#039;m 18, female.
I seem to have drawn the short straw with this medicine. I&#039;m very lightheaded, sensitive to light, and lethargic. On top of that, I&#039;ve had headaches and dry-mouth, and I&#039;ve lost my appetite. 
I suppose my symptoms have improved, but things are only better in the hours after taking the pill. Since I didn&#039;t have severe Irritable Bowel Syndrome, just cramping and frequent trips to the bathroom, the side effects negate the benefits. I cannot function as well as I would like. My lightheadedness has kept me from moving around much. I&#039;ll definitely be asking to have my dose lowered/the medication stopped, because I&#039;d rather be in some pain than be on the verge of passing out whenever I stand."
