The same thing happened to me! I use to LOVE Water now I can't drink it without having Crystal Light. But honestly, it's not uncommon. Your taste in foods will also change. Keep it up..you can do it!
Honestly, this is about changing your eating habits all together. It's not about eating the same thing we did before, just smaller portions, it's about changing what your eat so we don't go back to old habits. That said....stick with the diet your surgeon gave you. I was still on Soups because your stomach hasn't healed yet. Be careful....
