headache relief

I've been battling frequent migraines during pregnancy (~13wks) and want to share with u girls what my OB said today: 
Take a Tylenol & drink CAFFEINE!  
She said get some coffee - even if u aren't a caffeine drinker.  She said the headache meds they prescribe have Tylenol & caffeine but I should try over-the-counter options first.  
(Also found that a shower & glass of coconut milk take the edge off - I know I'm dehydrated but I just pee my water straight out.)
