Post-Surgery day 1 and Burping 15 times after each skip

I had my surgery this morning, went smoothly according to doctors. But every single sip of water I have results in me having gas attack and burping like nonstop for 10minutes.

I know there would be gas issues on first day or two but wanted see burping that much was normal? Nurses told me best way to pass gas after surgery is to fart but I haven’t felt the need to do that yet.
