I'm trying to go no-sugar. (It doesn't help that my daughter is on a baking kick and made delicious cheesecake-cookies just now.) Well, if I'm going to eat sugar, it's going to be yummy stuff, not a coke or gatorade or ew, shot blocks. I don't really think it was the calories I needed. I think it was salt (electrolytes). V8 does really well for me at restoring salt. I haven't tried Nuun or Cytomax.
nybiker, since I stopped eating sugar (mostly), I can handle having a late breakfast. It's still my favorite meal of the day and I eat most of my food from breakfast to lunch, but I will usually go for a run or swim before breakfast with no problems.
