I received my Xanax last night and took my first dose. Man, did it knock me out. It made me SO very sleepy and groggy. I mean, I don't think I could take this during the day and work. I could tell a big difference in this and Valium from before. Is this the normal reaction with Xanax? I was just thinking it would calm me down and relax me, not completely wipe me out.
