I still don't feel that much a difference, maybe yesterday the pain on the chest was a kind of resistance for using hybrid, what I did notice is that my body is not as hyperactive as before, also it helps me to sleep better than hybrid, next time let's see how perfoms along with OFv4.

I suggest you stick with ultrasonic format.  The effects should be cumulative, as far as I can see, though, so keep going.
