Years ago I discovered TrueLemon and TrueLime packets. It is crystallized lemon or lime juice sold in packets like salt or pepper and also in a shaker. I have used this in tea, cooking, etc... for a long time. It gives a MUCH fresher lemon flavor than bottled juice and is really easy to carry around. I have struggled for YEARS to find low or no cal drinks that I like and that have no artificial coloring or sweeteners. Like my thank you, I cannot handle ANY aspartame or sucralose - I end up wheezing. Now the people who make TrueLemon have a drink mix!!!!!!! It has no calories, tastes wonderful and is very lightly sweetened with stevia! I got the orange flavor drink mix to try, and it is awesome!!! Now I want to try the lemonade and raspberry lemonade!! These come in those stick packets that you just dump into a water bottle. To find out more, go to www.truelemon.com. Walmart carries the drink mix but not the packets of just dried lemon or lime (they are fantastic in cooking - just one packet in any non-chocolate baked good gives a super fresh taste with-o a real lemon taste). The website has a store where you can buy all the products online and right now if you buy $10 worth of product you get 1 32ct pack of lemon, lime or orange and $2.95 shipping.
