Oooops, sorry. I skipped over the second part of the question. I think you can increase the hex water consumption at a rate of a glass a day. You can expect some minor detox like some gas, bloating and possibly some emotional detox , which happened to me.
Start with 8-12 ounces on Day 1. Some people are up a full 10-12 glasses within 3-4 days. It really depends on your personal health.
