well, here's a curious side effect i have every single time when the Botox starts to kick in. Sneezing fits, not just one but up to 15 times at once. as Phil says , he thinks i have a short in my neurons. Does this happen to anyone else? this is of course accompanied by congestion and at times the flu-like symptoms others have complained of. mainly tho, just the sneezing, again and again and again.
