Full Liquid diets and migraines

For some reason ever since I started this liquid diet, I have a migraine that will not go away..even with migraine medication. Sometimes the pain subsides..but then it comes back full force. Its really starting to bother me. Anyone else ever have this problem?? I dont know what to do. Shannon

Maybe it is withdraw from sugar? The low calorie amount you are taking in now? I know when I have gone on low cal diets I would get sick with a headache too. Then when I went back to eating it would go away. I think I would have the same problem that you are having. Hope you fell better soon. ((Hugs))
