I like it. I've used it for about 2 years in tea and soft drinks. You can find people that think anything is bad for you.
It didn't really help me to lose weight, as I was drinking diet soda anyway. If you drink a lot of soda, and you want to switch to soda with Splenda instead, you should lose weight from it depending on how many real sodas you cut out in a day. Each real soda is about 150 calories a can.
