Granted many meds can cause horrid constipation. I had an issue when I tried LDN and then the opiates of course before and after hip surgery.

Extra extra magnesium works best for me. I also use 1 AloeLax by Nature's Way with my evening magnesium. I take mag thru the day, 3-5 doses. Some of my mag contains oxide but for many they can get too loose bowels.

Extra Vit C helps me too. 1000mg a few times per day.

When I get into bigger trouble Calms mag power in warm/hot water with lemon does a good job.

I've talked to people who drink hot water with lemon nightly and had a guy I worked with years ago who drank 1-2 glasses of warm water with lemon every morning.

Extra Warm water makes good sense. Stay away from too cold liquids. Stick with greens as much as one can. This is my regime. C
