Hi Susan.
I agree with Laurie, plus read my reply to Dawn Smith on the subject "First Botox tomorrow," where I added some more points about very small sips. A straw also helps me.If you can swallow food easily, just eat more moist foods, like applesauce, canned fruits with their juices, etc. Also, you can purchase a product called "Thick-It" to add to any liquid, which is what nursing homes use for elderly patients who choke easily.
The fact you are having these side effects means the Botox is working, but you received a higher dose than last time. The good news is that the GOOD effects will probably last longer.
Botox isn't a perfect solution, but the results are usually worth the trouble. Try to relax as much as possible during this trying period, take very small sips, slowly, as I told Dawn, and hopefully you can learn to adjust as needed.
Warm wishes, Marilee
