I find it hard to drink the maximum amount of lemonade (12 glasses). You might try taking a straight tablespoon of maple and see if that perks you up, or alternatively, take it in a cup of hot mint tea, or other herb tea of your choice.
Then bring out the Big Guns. This is part of Master-Cleanse protocol, for diabetics etc. Have 1 T. BLACKSTRAP molasses. I like to dissolve it in hot water like tea. The stuff is amazing! It can raise the dead.
If neither of these tactics works for you, keep drinking drinking drinking and wait it out. This too shall pass!
