I was prescribed 50mg of trazodone for sleep. The first time I took it I woke up with the worst headache, and it eventually turned into a migraine. I get migraines regularly but this was the worst one that I have ever had; complete with motion sickness, sensitivity to light, and vomiting. I felt awful the entire day, so I didn't take it again.

So fast forward to 3 weeks later, for my followup pdoc appointment, which was yesterday. She wasn't really happy that I stopped taking the trazodone. She suggested that I cut it in half. I tried it last night and I still feel like I have a hangover, but it's not as bad as before.

I am on leave from my job but that ends 9/11. I need to be able to get up to go to work, and I could barely get up at 10am this morning. (I usually start my work shifts at 8am) How long does the hangover effect usually last?
