I'm still using the same one as before. I really haven't experimented with other protocols...just the first one I tried that I did not care for and this one which is the same one I have said before but blanking at the moment on what the locations are called (worked overnight the past 2 days and a total of 26 hours...my brain is a little fried). I have thought about trying a different protocol to see if I can target some of my balance problems...but as I am still seeing improvements (even if they have slowed down) I dont really want to switch yet. Once the improvements stop I would like to try another protocol though and see how it goes.
