Hi @notmoff 😊
Yes, drinking too much water can definitely "wash out" the minerals in your body. I ended up in the hospital for two days as they slowly added saline IV drips. (They have to do it super slowly so your brain doesn't swell.) Most doctors will say 6 to 8 drinks during the day of 8 ounces of water is a good target. You can turn one or two of them into your Miralax drink if you want. You must have added your two 8 ounces of Miralax in addition to your normal drinking and then added a few more drinks of water to wash it down so it ended up being too much? I am on a daily Senokot S. I know it has a stimulant, but without it, I cannot go. Did your gastro doc say it's okay to take Senokot S every day?
