What's the reason for being dizzy i drink a lot of water so i'm not dehydrated and i get enough sleep so it's not that and i eat my meals what is it?

Hyponatremia: Trileptal is notorious for lowering sodium levels. Drinking lots of water may exacerbate the situation (dilute what is likely already a low sodium level) First things first. Check your sodium level, Trileptal level and consider doing a 3 hr glucose tolerance test to make sure you don't have reactive hypoglycemia. If this part of the work up is negative check an EEG and have your ears looked at.
