Has anyone had a backwards reaction to this drug? Not only have I not felt sleepy/sluggish from starting this drug, I've actually felt "speedy" and my heart was racing. This was on the second day of drug. My intern prescribed it at my suggestion after I read it had helped so many with nerve pain. She took me of Zanaflex which I was doing well on except for occasional hallucinations. I know I have weird reactions to drugs but usually they just don't work on me except at large dosages. Anyone else with these symptoms?
