Have you ever tried talking to your doctor about taking a longer acting benzo (Xanax is a shorter acting, and is usually prescribed short term) like Klonopin or Valium? Both of these are sometimes prescribed for a longer amount of time and have a longer half life..they stay in the body longer. Many SSRIs and other anti depressants also can be prescribed for anxiety...and of course the BEST resource in my book is talk therapy...keep us posted!
At the risk of invoking the rath of Mr. green, I agree with cj29. Talk with your doctor about the longer acting Benzos and the SSRI's. Since SSRI's take awhile to kick in a benzo may be necessary for awhile. Some people even reqqire a small amount of Klonopin combined with the SSRI's. I hope you have a good rapport with your Doc. and can feel free to voice your concerns. Hope to hear your on your way to good health. Let us know how you are doing!
