Migraine
"I preferred Relpax, but my insurance stopped covering it. Imitrex works at least 95% of the time, but maybe 10% of those times, the headache recurs and I have to take another one (which almost never happened with Relpax). My side effects are weird but not debilitating: sense of pressure in head, neck, chest, shoulders, arms; tingling in face; dry burning eyes; skin sensitivity to hot/cold; taste sensitivity to spicy/sour; lack of appetite; sweat; thirst; diuretic. A bit sluggish and sometimes drowsy, but not truly fatigued. Almost never nauseous; never dizzy. A couple of hours later, I often feel mild muscle soreness. The side effects are stronger if I take it on an empty stomach, but it also works faster."
