Hi and thanks for the post - I indeed have not zapped for the last three days and yes the symptoms have all but disappeared.
Perhaps you are right - I might very well have done too much, too fast. I will wait until tomorrow, Monday night, and then start with the basic 7-20 - I think I was, and am, confused about the fact that these machine has two different frequencies, i.e. 2.5 and the 30. I really want to get the best benefit - also the red cable has had me confused. While I am using the red in one hand I feel that whatever benefits that gives, I am giving only to that side.
What do I know - it is just simple process of trying to understand the why's and why nots.
