Oh how I feel for you. This is day 6 for mine and I think it may finally have gone tonight...but we'll see when the meds wear off. I am so sorry you have to go through that especially when you are trying to study.
Thanks. I try to look on the bright side: it could be worse. I've never gotten to the point that you did with having to go to the ER for drugs (I go there enough for my asthma as it is...). My vision usually blurs before I get one, so I catch it pretty quickly. That was my sign this morning to get my latte and two Excedrin. And I know my triggers, so I can avoid them.
My second semester of college, I got a bad migraine. I had to get an extension for several assignments. Catching up was fun. Last semester, I had a bad one and missed a Spanish presentation (called the professor during her office hours ahead of time so she gave me permission). Couldn't keep food down, went to one class that morning wearing sunglasses. That professor, who is a stickler about attendance, told me to go home and that I should not have even come that day. Apparently I looked terrible. I came home and slept 8 hours straight...then got up for a bit, then slept another 12. I think because I can sleep, I've never needed the IV drugs.
The single worst migraine I've ever had was right before Christmas of my senior year of high school. I missed one day. My parents made me go the day before winter break. I had English second period and we weren't doing anything, so I was going to ask to go to the nurse and nap during that class. That teacher said forget the nap, go home (I apparently get pale when I get a bad migraine). My dad was working from home that day and my mom was working, so he reluctantly got me and took me to the doctor, who gave me all of my prescription meds. A snowstorm was coming to MD, but we were going to SC for vacation the next day. As we were driving down there, we got to about Virginia, and the migraine subsided. I was fine the entire time in SC. The day before we left, I could barely get out if bed to pack. Yet another reason to hate snow.
I'm sorry that you're on day 6 of yours. That would completely suck.
