PLEASE HELP!

I have been on several medications for panic and anxiety disorder. But after 3 years of being on one they stop working and I have to change to another one.But every time I change to another one I feel very weird. I get weird sensations in my head when I move around and feel very sick.,even when I 'm weaning off of the medicine and starting a new one. and I'm going through it right now. Has anyone ever had any of this happen to them? Please let me know!

Changing antianxiety meds will often produce "weird" symptoms if the cross-over is not done slowly enough for you. But many of us have experienced what you're going through. These are some powerful meds and they have some powerful side effects. I hope your doctor takes the time with you to explain what you may expect. If not, ASK!
There are a number of really good antianxiety meds that are excellent for long term use. I would be interested to know which meds you've tried.
I would also suggest that you consider the possibility of getting into some therapy to get to the root cause of your anxiety. Meds will only mask what's really going on.
