Heartburn... HELP.


I’m 12w and I’ve been lucky enough that my nausea is going away and my appetite has been coming back, BUT I’ve been experiencing more heartburn (I’ve always had heartburn) and I normally take a pill, but I don’t think it’s cutting it anymore, and my heart burn gets so bad that it makes me nauseous sometimes, is there anything you guys swore by that helped your heartburn? I made the mistake of eating and then laying down right after last night, so that was a no no on my part lol I’m just trying to not feel like my stomach is on fire everyday (also I’m lactose intolerant so can’t do milk.)
