All these are physical. you are missing the physical reaction to sugar and trying to talk-talk-talk into a replacement doesn't work.

Also the more you stay away from sugar, the more you WON'T have the lows. things will even out. Not a big help at the beginning of course, but something to look forward to.

But it is nice to give yourself something nice in other ways. Not to go all the way to a shopping high or gambling however. Just kidding. Sort of.
