I am drinking a Pepsi and am quite disappointed!

I have not had a soda since December 30th. Tonight water was just not hitting the spot so I decided I would have a glass of Pepsi (I bought this the other day for small group and no one drank it). It is not at all what I was anticipating! It really tastes too sweet and is making me burp way too much. So I am done with the soda. Might have a fountain one while I am out to dinner Tuesday night.
