One more suggestion: Eliminate all aspartame from her diet. This got rid of both my migraines and seizures, which is wierd because I've been drinking diet soda for years with no problems. Since eliminating aspartame (in diet soda, "light" yogurt, sugarless gum, etc.), my short term memory is improved an amazing amount. I'd never go back! It's an easy thing, and worth a shot - it doesn't work for everyone, but why not try?
