Post Lap Gas Pain

For those who have had a laparoscopy, how long did the gas pains last? I had my surgery 7 days ago and ended up getting such bad stomach cramps from the opioids that I stopped taking them. I’ve been off of them for two or three days now and I’m having the worst stomach cramps that feel like trapped gas. Any tips for relief? I’ve tried GasX but it doesn’t seem to be working.
