I am planning to do my 3rd flush two weeks after my 2nd flush which followed four days after my first flush. I have about a week to go and last night I used my zapper for the first time. It is quite a sophisticated instrument and very easy to use because it is programmed with all the timings. Can anyone who uses a zapper tell me if it is usual to feel pretty crappy the morning after, or is it just the usual up and down gallbladder symptoms?
