I am also a lifetime migraine sufferer, however I have not had one headache at all since I started my pre-op diet. I do have Zomig which is a nasal spray and works in about 20 minutes if I happen to get one. I do have my one cup of coffee in the morning, and now I use Premier Protein as my creamer. I also had some last minute thoughts like you, but I told myself that if I could be successful another way, I would had already done it that way. Good luck in your decision.
