Post sleeve pain and hiccups
I'm 13 days post-op and didn't have hiccups but had all the other symptoms you describe. My nurse told me to sip more slowly if I got hiccups. The dry heaves and bile subsided around day 3, and the left shoulder blade pain is from the gas they used to inflate your stomach. For some reason it settles there for a lot of people. Lock your fingers and stretch your arms over your head. Gas-X tabs and lots of walking help too.
I PROMISE it gets better. Take your pain meds, walk and wait. In a week you will feel like a new person.
Use a heating pad on the shoulder pain - it really helps that anesthesia gas that's trapped there. Keep moving and it will eventually work its way out.
If you're getting a lot of bile that means you have a lot of acid activity going on. Did your doc put you on a PPI yet? If not, I would call and ask to get on one to cut down on that. Hiccups for me always indicated eating/drinking too fast or too much at one time. It was my signal for "full" or "too much". Not sure if that's what's going on for you. But things DO calm down after a week or two.
Hang in there!
