Gas as soon as i go to bed...?

Okay I know kinda gross but its very annoying... right as i lie down to go to sleep my stomach starts making all sorts of wild gurgley, popping noises. It feels like gas is exploding in my stomach and you can hear it! If i try to relieve myself i get nothing... and instead i just have gas pains and noise with no relief... its kinda embaring when i sleep my with my bf cause it sounds like i'm farting but its all in my stomache! any suggestions? Ive tried like rolaids and pepto i dunno... i dont eat before i go to bed so its not that... i really dont know!
