I took some Epsom salts as a laxative. The package said to take 2 to 6 tsp daily. It also said you could take it a few times a day or all in one sitting, so a friend and I took 6 tsp at once. I've been looking it up while I wait and everything is saying 1-2 tsp. I can't find information anywhere on how much is too much. Did I take too much?
