Has anyone tried vitamin B2 and calcium for Chronic daily headaches?

I have CDH, and take Keppra . I have only been on keppra for about a month so i'm not sure if its going to work yet. I havent had any migraine attackes, just my normal ANNOYING headaches about everyday (5-6 days a week) . My primary care doctor mentioned the B2 and calcium but i have not tried it yet because i just started the keppra and want to see if its going to work. I'm just curious if anyone else has gotten relief from Keppra or these vitamins??
