6 days out question
No one told me that rule but I think that it's pretty close to how I'm drinking 5 days out. I think I probably take in about an ounce in about 5 minutes without feeling uncomfortable. I'm not sure that since you are up to the 64 ounces a day that you need a full 15 minutes between ounces. Remember that if it feels ok going down your usually ok. Good luck.
