This is the first time i have ever taken fluoxetine/prozac. I have been on generic prozac for about a week and a half. I take it at night due to it makes me sleepy at work. I wake up every morning with a mirgraine (which i suffer with). That is the only issue i am having taking the meds. Will they ever go away as my body gets used to the medicine? I am running out of imitrex to take for the migraines.
