I agree, pulse on, pulse off.
While I cant comment on your particular problem because I have no knowledge,
I can tell you that pulse dosing really works for me.
I take Iodine for a few days, then when Im feeling really detoxy, or just after about 5 days or so, I take a break for a few days. That break really seems to let my body "catch up". Then when I start Iodine again, it seems easier than the last round.
