What Are Effects Of Taking Compazine And Zanaflex?

Hello Dr. Grief, My doctor prescribed me compazine and zanaflex for my chronic headaches. I'm trying to figure out which is for what since I remembered her mentioning one was for my heart palpitations. I have a history of anxiety attacks. I googled zanaflex and I'm confused about the correlation with anxiety. I wanted to relax, not become more anxious! Your advice/opinion is greatly appreciated.thak you! Cat
