I have been loosing pretty good on this wol and that I am MORE than happy with (besides the fact the the lb's could not come off fast enough) One negative thing I've noticed is I get dizzy spells however, which I never had before this wol. I have a buddy who said he had to quit because of the same thing except his got progressivly worse until he said he passed out after standing out of his chair one day. Can anyone exsplain this phenomenom?
