My psychiatrist has prescribed me serta 50, 2 tabs a day and zapiz 0.25 once a day. I have ocd and intrusive thoughts and anxiety and been on this regimen for the past 3 months and am supposed to continue. Can taking zapiz 0.25 for so long be dangerous or addictive or cause memory problems because i am a college student and have to study a lot? {Before this i had been on cyclotin 40 for more than a year.(initially 2, then 1 everyday)}
