Sure, cut back on the syrup if you like, and if you feel fine! I cut back also, but only to 1 1/2 spoons. You'll probably be ok with 1 spoon too, see how you feel.
Good for you, braving the salt water flush! I think you'll be surprised at how horrible it *isn't*! You are supposed to do it in the morning, though. If you do it at night, it supposedly washes away many of the nutrients in the lemonade, and also lessens its effectiveness by washing it out before it has a chance to dissolve gunk in your intestines.
Please post back after you try it! Good luck!
