Hi Chris, sorry if I was unclear. My docs suggest Pepcid as well as Benadryl because Pepcid is also an antihistamine, though we all use it to combat GI acid and GERD.

I believe you can ask to have the infusion slower. But I don't know if your doc has to prescribe it that way or if you just ask the nurse who administers it.

Barometric pressure is a major trigger for a lot of people. I am sorry about your jaw pain! Weather changes in general are a problem for many. My daughter has been in San Diego for the last few years and I feel so well with the steady temperatures there, that I consider moving there!
