I read long ago about inserting V in the urethra!
Believe it or not, it works even with 5~10 mg and of course without headache.
I wonder if anybody tried that or heard of any long term consequences since it is not the way recommended by Pfizer.
The way to do it is quite simple: crunch the pill in a folded paper, collect some powder with a small straw and insert it half inch down (up) in the urethra.
