Difficult week

This has been a very difficult week for me migraine wise. The weather has been on the most part wet without really snowing or raining and the barometric pressure has been sitting at or below 100kPa. What does this mean to me is constant migraine, with nausea, vomiting and diarrhea. I have been taking my medication without success so I have held back from taking it because I don't want a rebound headache. Today I am feeling a little better I was able to eat breakfast this morning without being sick. I have basically just kept icing my head and lying in bed. I have plans for this weekend so I am hoping for the best.
