If you're sober and don't drink, you can ask that people don't drink around you or to not be invited to events where there will be drinking. You can remove yourself from situations where there's drinking because it makes you uncomfortable.
But you don't get to go into your friend's home unannounced, search through their kitchen for alcohol and dump it down the sink because drinking makes you uncomfortable. You can't forbid them from restocking after you leave.
