pre-med and on meds. big sigh. please look into The Emotion Code.
maybe even watch some videos.
It's really powerful work.
The Water Fast can wait, in your case, it's not the right thing.
wish you all the best
edit: sorry, that sounded judgmental.
I think I noticed the med part more than the rest. But I still say, the Emotion Code work is amazing. I highly recommend it.
I have done several Water Fasts -- (you can search my posts, something might help. ) They are good too, but this work is liberating in a true sense. beyond all meds!
