migraine
"I'm a 3-4 migraines per week person. When I first tried Imitrex, I thought I had found my own personal miracle.  Even on days that I didn't have a full blown migraine I would still have pain, and this was the first time I felt completely pain free in years. Unfortunately the honeymoon wore off after about 8 months.  I used Imitrex quite frequently during that time and had wonderful results, even though sometimes I had to take two pills to really do the job.  But after eight months, 2 pills weren't doing the job, my headache was still lingering.  "
