janet,
I was on .5 mg of Xanax for years. I was still taking the Xanax up until I found out I was pregnant, but had to stop the Xanax cold turkey because it can cause birth defects. I still get anxiety here and there and I am hoping that after the baby is born, I can just continue with my Effexor and not have to get back on the Xanax...time will tell though!
I am so glad you are feeling better - it stinks that when we start medication it doesn't start to take effect immediately, but it does get better! Hopefully that dose works for you, but if after a few more weeks you don't seem to have the relief you need, talk to your Dr. again...good luck at your next appointment, I will keep you in my thoughts and prayers that you continue to feel better!
