So I finally made it 3 days without taking PM, substituting FG and SP instead. Wasn't too bad, but the 2nd night i started getting a headache. 3rd day it got worse, by day 4 I thought maybe switching back to PM would help get rid of it, but hasn't worked yet.

So now its day 5 and my head is still killing me. Any advice would be appreciated. I'll check back tomorrow morning, hopefully its gone away by then.

According to this article on Livestrong.com, PM contains caffeine. I can't find a reference to how much, but I must admit I haven't looked all that hard. Caffeine withdrawal could explain the migraine. Caffeine consumption can also explain why the migraines went away when you first started PM since caffeine is a vasoconstrictor and is used in over-the-counter migraine treatments for just that reason--it forces blood out of the brain, relieving the headache.
