ive been expereminting a bit with some carbohydrate drinks and the sis ones I have tried have been making me feel really sick, is this common with energy drinks? I also get the same problem with their gels, high 5 gels sit okay with me. I even tried the organic one. I find carb drinks easier when I am out with a group as don't get much time to eat on the go, when I go out on my own tend to pick at things along the way. its also quite annoying that you have to buy the whole bottle of some energy drinks, thats why I went for sis ones as you can get the sachets just dont want to waste my money on something that my stomach cant handle. anyone recommend anything or should I just stick to watered down fruit juice?
