I was sleeved on the same day as you!! I think with the jello, you have to make sure you chew it up a lot before you swallow -- turning it to liquid instead of just swallowing bites of it. That works for me really well. As for the shake, just make sure to take really small sips, I think? Or, alternately, make your shake and then leave it in the fridge for 20 min before you drink it, allowing the air to escape from the bubbles, since probably the thing that's causing you pain is the trapped bubbles~
