My doctor wants me to start klonipin long term for PTSD and horrible anxiety, good idea?

I tried to respond using the brand name of the med, but it will not go thru. I'll try using the generic for the med. I take 1 mg Clonazepam every nite & it does help my anxiety & it helps me go to sleep. It helps most people w/anxiety a lot but not everyone w/sleep. It really is supposed to be used short-term, but I've been taking it for almost 2 yrs. I recommend it at the lowest possible dose that give you a benefit. At a high dose there could be withdrawal probs. Zoloft worked for my depression for many yrs but then it pooped out. Wishing you the best.
