Can drinking cause friendship problems?

I drink roughly every other day and usually about half a bottle vodka or a wine bottle and beers. I do try and moderate myself but when you play drinking games with friends over an hour or two it becomes hard to remember how many shots or drinks u have had. I know that once I hit a certain point I start falling over constantly but mostly on my walks home. One of my friends always walks me home and I’ve told him many times he doesn’t have to because I am able to walk alone and I don’t want to be a burden but he insists. Anyway, recently I have been trying to sneak away from my friends and walk home by myself because I don’t want to ruin anyones night but that made him angry at me. I want to continue drinking because I love it but I don’t want to ruin my friendships. What should I do?
