Not sure on the Mag Citrate but I can tell you about my own experience with the other. I did four flushes before I did a parasite cleanse. Other than feeling a little tired the morning after the flush, I felt great. Better than usual in fact. As far as water, I drink small amounts of water all day on the day of the flush, even after I have stopped eating. The morning after, I always feel dehydrated and I start drinking water within a few minutes after my first dose of Epsom Salts . I don't drink gallons or anything but I don't let myself get thirsty either. This helps prevent Epsom Salt headaches for me. I start drinking orange juice 2 hours after last Epsom Salts . During the night, if I use ornithine to help me sleep, I feel fine during the night. Even if I wake up to go to the bathroom, I can go right back to sleep.

Of course others have different experiences but this has been the same for me for four flushes and I admit, I am not in the best health- don't have the best diet, etc.
