Hi Angie.
I would. I'd drop the half, for a couple weeks, then half again, until it's finished.
I'd be worried about a sudden crash. So to me, dropping slowly, gives your body chance to catch up, I'm sorry to hear your suffering palps, they?re horrible aren't they, and given you've got a leaky heart valve too, must be so worrisome.
I'm hoping someone will be on soon to give their spin on it too.
Good luck.
Let us know how your getting on.
Xx
