I have been reading about how some drugs or foods potentiate klonopin and I read so much that I forgot if DXM potentiates it or not. My Dr put me on Klonopin 1 mg 2/day and it helps but not all day. It seems to relieve my anxiety for only 4 hours. I was on 2mg 3/day before and that helped me all day long but my Dr said that was an extremely high dose. But with my degree of anxiety I don't think it was because it helped. So what are the best potentiators for klonopin and also will zanaflex prolong the klonopin or just enhance it. Thanks
