I took it twice a day for a long time and it changed the taste of foods and made me want to eat less. I needed that. Then I came off bc my migraines came back. A year or two later I went back on it. I've had no weight loss at all this time. No changes in taste or anything. Is there a high dose I should ask for ? Did anyone else's body get used to it and not be effective anymore? I'm on 100mg at night right now. Can split if I need to.
