Have any of you used maxalt? I tried it yesterday, took one, slept for a bit, felt fine. Then later that night I started freaking out, couldnt get my world to stop spinning, etc, tried to sleep but couldnt, so I took another to knock me out . It worked. But I woke up four hours later feeling like I was going to puke and again, couldn't sleep. I still feel shaky, nauseated, weak, neck pain, and really really tired. Anyone have these side effects?
