p.s. u should all try them!:) yuumm
is that the jello or the pudding? cups or boxes you mix yourself? I'd check the ingredients - only thing that could potentially cause issues is the artificial sweeteners - on occassion I've found them to have quite a laxative effect if eaten in quantity - however, you may have to eat until you find your personal limit though. I had this problem mostly with sorbitol in candies (I used to be a peppermint addict). You might also want to watch the sodium count on them as well.
Again, even though it's sugar free and seems good for you, everything is best in moderation. Personally, I'd have to determine the serving size for that calorie count to determine if it's still worth having more than one at a time, regardless of my spendable calories. I tend to seek the biggest protein bang for my caloric buck so that I'm not hungry in 1/2 an hour when the carb high wears off.
The side effects of allergy medications keep some people from using them. Natural remedies can be a great alternative, but some are more effective than others.
