Not a fan of coke, but I really like Pepsi. I try to avoid drinking soda on a regular basis. But when I'm sick with a sore throat............it is Pepsi that I crave most. Other sodas are fine as well, but that's my first preference. I know some people crave comfort foods such as pasta, cookies, and soup when they're ill.....but I'd rather have my ice-cold Kaala Pani, LOOL.
A friend of mine believes that it's the bubbles in the soda that temporarily calm the throat and settle the stomach. I think she might be right, cuz I find it soothing.
