Indigestion😣

I was an idiot and ate a big meal before I went to bed and now I'm paying the price with some indigestion. My stomach feels uncomfortably full and it's kept me up all night, despite my exhaustion from the day. The top of my stomach feels heavy and I feel naesaus and gassy. I tried going to the bathroom, but nothing happened. My stomach still feels uncomfortably full despite me drinking a few sips of water to aid in digestion. What can l do?
