It's totally your decision, but from my experience, if I stick to the recommended dosage and no more, it's fine. The taste is worse than anything else. Alternatively, to avoid the taste, you can take it in capsule form by making your own capsules or buying it already in capsule form http://www.drclarkstore.com/magnesium-sulfate-usp-epsom-salt-1030-mg-100-capsules/. For the amount required, I just put up with the taste.

Frankly, the hardest part for me is the fasting prior to the flush, but it is critical to success. Also, the day of the flush can be exhausting, so be prepared to rest.

I've used a few TBSP of magnesium citrate powder, brand is called Natural Calm. Worked well for me. A little less stressful on the stomach and kidneys than Epsom Salts .

I did my first one 2.5 weeks ago and the ES wasn't a problem. Just don't breathe while you drink it and swallow the 2/3 cups in one go. :)
