I’ve had chronic constipation due to being on a GLP1 medication. It was horrible. I started taking Mag07 and it seems to help a lot. It’s a brand I bought off Amazon but I believe CVS and Walgreens sell it. Hopefully you can see a specialist to find out what the source of your constipation is because you don’t want to develop a fissure or haemorrhoids. Straining like that can’t be good for you. Hope you feel better soon. I know that struggle and it’s absolutely miserable.
