YES!!! The first 3-5 days are the worst. Have your 5 allowable packets.
Also, pickles are free, so you can munch on those too. There is a lot of discrepancy from coach to coach, but my coach said that egg whites are free, so maybe you could hard boil 1 or 2 to snack on as well.
Also, do a search for the thread "pudding cakes". They are Phase I allowable and they are very satisfying- much more so than just the pudding alone. And you can actually EAT them, as in chew. Plus they are extremely tasty
