I've been on Topa for a month and I'm now at 100 mg. It is my week to go to 125 but I'm doing it on my own without a script so I'm being really careful and hovering here at 100 mg a bit. I sometimes notice the tingling in only one foot and for me it only means one thing- I need water! If I drink a bunch of water it goes away in a few min. I know everybody is different but it might be worth trying.
