i was prescribed .5mg of clonazepam because i have severe panic, anxiety and PTSD. I have never taken them before. A few weeks ago i took .5 of a xanax, and it made me feel better. Im just wondering if anyone has had any experience never taking any type of drugs before im just worried about feeling weird or blacking out. I read they do last a long time and if i dont like the way they make me feel i will have to wait until the feeling wears off. im just scared i really do need to take something for my anxiety but im really anxious to take them. Hope this makes sense im just trying to express my concern.
