I try to avoid the foods that give me acid reflux at night, but when I don't it's baking soda or swallowing a whole tums tablet.
As for sleeping, I generally start out on my left, but have to swap a number of times, mainly from my left arm going numb. I turn, and grab a pillow to support the left arm. Maybe use a pillow between the legs to relieve pressure on the knees at that point.
I'll go back and forth, generally ending up on my right, remembering how I have to reach backwards for the alarm, more often than not.
My 3-year-younger brother slips with his fitbit. I'm jealous of his minimal sleep interruptions.
Yeah I know the potential side effects..basically all of those acid reflux medications have side effects and can cause harm to the kidneys, liver, etc..its better than getting Barretts..which my brother was recently diagnosed with(Caught it early stage) he had NO symptoms, for me I have constant stomach burn/pain and the doc did the endoscopy and found nothing..so he said its better to have a lot of pain and find nothing than have NO pain and be a ticking time bomb
After many hours pass by since last food intake, acid production should be dropping down. IOW if you go to bed at 11pm, by 3am there should be lot less acid in the stomach, and switching to right side after 3am should not cause serious acid re-flux.
