I think iam getting rebound headaches. The rizatryptan isn't as effective with the increase of my migraines. The migraines are pretty much everyday having to take 3 rizatryptan in a 24 hr daily. I really can't say when it started. It happened so insidiously. Now how do I get off this medication. It's been very painful. I try but then I can't stand the pain any longer and give in and will take the tizatryptan. I tried to take ibuprofin instead but it doesn't do much. I will be seeing my headache doctor this week.
