About 3 years ago, I went on a quest. The quest for a six pack. I quickly realized that if I continued to drink regular pepsi, my goal would never be achieved. I swore off regular pepsi and looked into alternatives. The first thing I tried was diet pepsi. As it went into my mouth, I smiled and then I swallowed and there was a horrible aftertaste. I stopped smiling. Never put your tastebuds through this torture. I stayed away from soda of any kind after that experience. Eventually I achieved my goal but I still missed the days when I drank soda. One day I was shopping recently and I saw pepsi one. I tried it and I loved it. It didnt have the nasty aftertaste of diet pepsi. I set up a taste test and my friends couldnt tell the difference. Try out pepsi one instead of diet pepsi. The main sweetener in diet pepsi is aspartame which probably isnt good for you anyway.
