You were lucky.

Water dehydration leads to nausea during and after the flush, and exacerbates the Herxheimer's Effect (toxin symptoms).

For at least the 3 days before flushing, you should drink 8 or more glasses of water a day. During the flush, it would be ideal to drink a glass of water every two or three trips to the bathroom. You can, and should, drink water at all times except for within 20 minutes of the ES or oo/citrus drinks. Of course, after the oo/citrus drink, you should go immediately to bed!

Clark's flush does not mention this, but Moritz' flush strongly recommends that you continue hydration during and after the flush.
