Having some of these included in your food storage will help break the cycle and give you some variety in what you drink. Variety should already be included in your food storage, but it's just as important to have variety with your water storage. Most stores and supermarkets have large jars of flavored drink mixes that are very inexpensive. You can get Kool-Aid mixes, Gatorade mixes, Tang, and a number of other mixes.
These come in all different flavors so everyone should be able to find something that they like. Tea bags are also a good thing to store as they last a long time, and most people like a nice cup of tea. And for all the coffee drinkers out there make sure you have some coffee stored for those early morning pick-me-ups. Another option is to store protein powder drinks. These come in a lot of different flavors and types, and most are high in calories and vitamins, which would make it perfect for a quick meal on the go.
No matter which one you choose, having something to add to your water, giving you some variety is going to be beneficial. If nothing else having something flavored to drink, and possibly sweetened with sugar from your food storage is going to boost your moral in the event of a disaster. I like water just as much as anyone else but nobody wants to drink only water everyday. If you have children this is something that's very important.
