I pretty much get a bad headache after longer rides of 50 ++ but not the full blown migraine vomiting action. I like the idea to take the Vit. I during the ride instead of just at the start and finish. I asked a Doc to prescribe Celebrex and will try that plus Vit I, and get my butt home or to my massage therapist to work on my neck. Huh, that and the glasses. GREAT IDEAS ! Caffine is pretty much a given during the morning and with all the gels but I never thought of it after I finish. OK, well some stuff to work on. Bye for now and I will see how it goes! Lisa G.
