I had that thought briefly wondering what it was going to be like after it was already done. I thought back as to why I procrastinated so long and remembered seeing literature with the expressions of the people in before and after photos and the after photos alot of people looked like they were miserable. I'd often think if I was the photographer of those and just told them to say cheese or something funny to cheer them up and if that didn't work just tell them to f'ing smile. I too am outgoing and wondered how much it would affect me. I'm 10 days short of a month from Duodinal Switch with the Roux ein y.
As far as the burning. Second night I had acid reflux bad and I was pissed they wouldn't give me a tums. Instead they gave me warm mint caffine free tea that did the trick for that night.
Another night I found that when I slept with my CPAP I forgot to put in my cheap mouth guard that I always use to protect my teeth cause I'm a grinder and it naturally keeps my mouth closed as my cpap mask is a resmed P10 that is just a nasal pillow. Anyway, I was opening my mouth without it and it was creating a straight line to my gut causing acid reflux.
Those were the two major nights. Occasionally I will feel a little burn if I drink or eat too late but I find if I take 2 or 3 sips of some mint tea that I have ready cooled in a cup in the fridge and then lay on my right side with my cpap and mouth guard in I am good to go. Sometimes when I sip that tea I'll let out a little burp that has been holding and it's gone right away. Other times if you hear your tummy rumble and air going back in forth in your gut, lay on your left side. You may feel an immediate need to pass gas and instantly better. (Or at least for me).
Also my Surgeon has me on Sucralfate tab 1gm, Esomepra Mag Cap 40MG. I don't know which is for what but one is for acid reflux. I grind the Sucralfate tab with a pill crusher morning and evening and toss it back in some liquid (They say dissolve them but I don't have a half hour to wait.) Esomepra I take apart the capsul and put it in with the sucralfate in the morning. I'm using BariatricPal's Duodinal Switch pack for vitamins and their strawberry watermelon flavor tastes like now & Later candy.
You might also consider a sleep study. I used to get acid reflux all the time until I participated in not 1 but two sleep studies. The first one I was wired all up and nervous how to lay that I did not lay how I normally sleep. The second I didn't care if I pulled a wire and got comfortable and they woke me within an hour and hooked me up to sleep with a shiny new cpap. For 7 years until my recent surgery I never had acid reflux, night sweats, wake myself snoring or wake up semi panicked, or with that acid burn from acid reflux. Truthfully I never slept better since I was a little kid, not even when I was super fit.
Overall though, you need to personally asses what your body is doing and simple ways your can help your body. Inquiring here is a good start but there is only so much advise people can give but hopefully we give you some ideas. Above all, focus on the positive light at the end of the tunnel. Hang out with positive people and don't let the crabs pull you down. Everything happens for a reason.
