Thanks everybody for the replies.
SoCal - I''m tapering by 5mg a week - so I was at 20mg for 1 week before tapering. I had been feeling fine before the taper and my body had seemed to even out after about 3 days from the previous weeks taper to 20mg.
quincy - thanks for the advice. I actually do use Ocean spray sinus cleanse and was using it like mad the past few days :) I also take Mucinex (the Walgreens generic version) sinus decongestion pills when needed. I'm not anywhere near my period and wont' be for a looooong time. I actually take my birth control pill packs back-to-back to avoid monthly periods. Also, the last time I had my period in April it got my UC going again and my obgyn told me just to wait till I'm off the Prednisone and clearly on my way to remission before I have another period. The Prednisone really screws up my period anyway.
I don't drink coffee but did totally forget about the caffiene thing for migraines. I'll have to go get some iced tea tonight and maybe drink that for a few days. Thanks for the reminder on that one!
Weather does affect my sinuses, which in turn can give me a migraine. The neurologist I've been to has told me that some people can get sinus headaches that turn into migraines. Then once I've got one, there are certain scents that just make it much worse (perfume, smoke, car fumes).
I was going to start tapering by 2.5mg once I hit 10mg - maybe I'll have to do that next week instead of going to 10mg. So far the headache seems to be gone. I've got hot yoga tonight which seems to really help clear up my head - hopefully that might help a bit too!
