Yes, it is frustrating. I'm staying with the extra water though, and my supply of lemons is dwindling off. I need to freeze some of the juice while I still have a few. The new lemons are growing. They are about the size of a pecan right now. That tree is great -- always doing something.
Eventually I'll figure out what the culprit is. For now I think I will stop using any of the coconut water, even if it does state 0% on everything. It is interesting to note that my body is getting in the habit of waking up early now -- it's so neat to have 5,000 to 6,000 steps by 8:00 in the morning when that used to be my number when I went to bed!
