Thank you so much, paul, for keeping in touch re this. I'm not sure that I agree with your drug clinic Dr about stopping the Xanax cold turkey, ...
Keep an eye on your reactions, and don't be shy about bringing them energetically to your various treating Drs attention. You'll have to be your own advocate, but if you start getting withdrawal symptoms, and believe me, you'll know 'em when you feel 'em, let them know immediately and request a slower transfer, which will let your brain and CNS adjust better to the loss of the old med and the addition of the new.
Keep updating, please. You've been on my mind.
