I've done lemon but get sick of it and am using mio and the other mixes they have now. It's helping a little bit.
I tried putting a slice of lemon (or any fresh fruit that you like- strawberries are pretty good) in my water - only refreshing if it's like ice lemon water lol
I was able to drink cucumber infused water too but that only lasted a few days, the thought of cucbumber in my water now makes me gag
Try flavored water they gave some with 0 calories and zero sugar but may have sugar substitute try water with lemon or other fruit
