Ok, That was for Sara!
I have my prescription form. Personally, the main side affect I've had with Topamax is the crying spells! Drives my husband nuts!
As far as eye problems goes, my form says "Seek immediate medical attention if any of these RARE eye problems occur: SUDDEN vision change/blurred vision, eye pain or redness."
And "loss of appetite and weight loss may occur." is also listed.
I had spinal surgery a few months ago. I didn't know it then, but one of my medicines caused my taste to be "off." The only things that tasted the way they were supposed to were juice and canned fruit. But, since I needed to lose some weight, and I was bedridden anyway, it wasn't a big problem. By the time I was ready to start getting up and around, I was done with that medicine and my appetite returned. But because of that experience, I can really relate to the problem of not having an appetite. My husband kept cooking, and kept trying to get me to eat, but how can you eat when nothing appeals to you?
I think a good approach would be to make sure you are consuming calorie rich foods when you DO eat. Get some high calorie shakes like you see advertised on TV. Or make your own with fresh bananas and ice cream. Try to drink a shake whenever you take your medicine. Spread a bagel with nutrition packed peanut butter. Munch on raisins, walnuts, & almonds throughout the day. Have something at your fingertips all day long.
If you don't already, start taking a good multi-vitamin. And ask your doctor for any other ideas (s)he might have. Your local community hospital might have a dietician or nutritionist who can help you also.
