So sorry to hear this! I’m glad that your providers are figuring out what is going on. Hopefully the spasms will subside soon, and you will be healing. Hopefully you will be on your journey towards eating and drinking regularly (for gastric sleeve, that is).
This was not my scenario, but I had esophageal spasms and then vomiting for two months. I followed the doctor‘s advice, and it did eventually subside. I then had a normal response to the sleeve, and have lost most of the excess weight.
So hang in there, and sip slowly throughout the day if allowed. Even though your recovery is not the usual, you will likely have good results eventually, once you pass this hurdle!
