K.C.
I had bad headaches with my last pregnancy. Taking zyrtec every day helped keep them away, but they also gave me a Tylenol 3 Rx, which would usually get rid of them. I only took it occasionally. The thing that would help the most (which is very hard to get, I know) was to lay down with an ice pack. The ice packs helped a lot. I know how terrible this is. I'm sorry you're feeling so bad. I always hate it because a headache sounds so minor but it completely effects every thing you do and how well you do it.
