Scared Band to Sleeve

I am having surgery on April 14th and I am so scared since this is permanent. I am having bitterness in my mouth, raw filling into mouth, constant sore throat sensitive teeth also dry mouth. Did anyone experience this with the band? I don't have actual acid reflex but I feel like my mouth is full of bile or something. I am so afraid to have this happen after the sleeve it bothers me so much. I can't eat or drink everything tastes sour. Since the sleeve is irreversible I am so afraid. Usually I am not like this after my lap and I became so fragile and worried because most of the time I am not feeling well. Can you please share your experience with me? Is the sleeve easier than the band? Does it feel

Different? Do they have the same issue? Thanks I will really appreciate it I only have this forum to help me!
