I can only answer a little to this post as I have only done 1 21 day clenase, I'm sure more people will respond that can be more helpful to you. I honestly think it's not a good idea to lose the maple altogether, your body needs the minerals in it and the sugar, maybe you can try Blackstrap Molasses instead, but you should have something. This, in my opinion, is probably where your weakness is coming from.
Hope you feel better.
you can do it!!
