My new psychiatrist wants me to switch from Xanax to Klonopin. I took my usual 1 mg. Xanax last night and this morning, took the first .5 mg. Klonopin. After about thirty minutes, I started to feel my lips and throat becoming numb. They don't feel swollen, as in allergic, just sort of numb. I can swallow normally, but the feeling is frightening me. I'm worried that the anxiety over the numbness is feeding into it and exacerbating the sensation. After 90 minutes of numbness and increasing anxiety over the numbness, I finally took .25 mg. Xanax. So far, still numb, still anxious. Is this normal at all?
