Migraines and Too Much Sugar

I've noticed that whenever I have excessive sugar, it triggers a migraine. This could be chocolate, candy, fruit juice, etc. When I noticed the connection a couple of years ago, I went to the doctor and said, "I get migraines when I eat or drink sweet things" and his response was, "Well, don't eat or drink sweet things."    I was put on Sumatriptin to take when I felt a migraine coming on, and Pizotifen to take each night as a preventative measure. The pizotifen worked wonders, I must say.

But lately, the medication isn't helping and I've had 3 migraines in the past month. I can take up to 3 Pizotifen tablets (5mg each) and I've been taking the maximum and it's still not working. I went to the doctor (a different one) last week and explained about the sugar thing. While he said they can't do tests for the migraine they can test the blood sugar, so I'm going next week. And my dosage of Pizotifen might be increased.

I've read online that refined sugar can cause the blood sugar to go up and down too fast, and can cause migraines. I suspect this might be my problem. Just wondering if anyone else has a similar problem? And what foods do I avoid (other than the obvious chocolate, alcohol, etc), i.e. are starchy food like potatoes bad?

I guess I'm just looking for a bit of support, I'm so sick of being sick!   It's really got me down. Any advice is appreciated. Thanks.

Yeah I get neck pain too. I take Sumatriptan which I think is similar to Imitrex (I'm in the UK so the medication names are probably different). But I find that unless I catch the migraine RIGHT when it starts, it doesn't work.

Anyway I'm going to really pay attention to my diet and see what happens. No alcohol for me!

I'd say mostly, it's cumulative. I can eat a piece of chocolate on a Monday, then maybe some cookies on a Tuesday, a bit more sugar on Wednesday -- and all this time not feel sick. So I get fooled into a sense of wellness. But then Thursday and BANG. I'm sick. So I find I really, really have to pay attention to what I eat daily. If I eat a piece of chocolate I'd better not have anything else that week. Truthfully it's too hard to keep track of so I'm better off avoiding it all together. I don't recall fresh fruit ever making me ill.
