I've had IST since I was 7 years old. It seems to come in cycles. I feel okay for a year or two and then it gets so bad I can't get out of bed for about a year, and then it gets better, and then it gets worse and yada yada yada. Well, right now I'm going into one of those cycles and I don't know why. My doctors took me off meds because they're making things worse. I eat well. I try to get tons of sleep. I avoid caffeine, alcohol, fatty foods, greasy foods (I eat a lot of salad), and too much red meat. I'm doing everything right. I am doing everything that I was doing a few months ago. And yet, all of a sudden, for the past 3 weeks, I feel completely awful. My migraines are getting worse. I'm waking up with heart trouble. I go into minor seizure episodes. I can't eat without throwing up until later in the afternoon. (No, I'm not pregnant.) Constantly dizzy and constantly fatigued. Any idea why it does this? Does anybody else go in cycles too? Any home remedies that work for ya?
