Gas pain and belching Occurs almost every night

I occasionally have gas during the day and it’s alleviated with belching. Gross, I know. But I’ve been waking up anxious with gas pain that is only alleviated by belching and these episodes can happen from 15 to two hours. Right when I want to lay down and go to sleep my stomach wakes me up with pressure and the need to belch and my mind is anxious (guesing gas pressure is hitting a nerve causing anxiety) Any help greatly appreciated, boy do I miss sleep!
