Is there any relief?!

Every night around 8 - 8:30 without fail, I get horrible heartburn and can feel the stomach acid creeping up into the lower part of my throat and burning the crap out of it. It was so bad last night that I was almost in tears and couldn't sleep well at all. It typically goes away sometime while I'm sleeping but it was still present even at 8 this morning. Is anyone else dealing with this? And if so, are there any safe OTC heartburn medications that you've tried and have worked? I don't want a repeat of last night 😰
