Beyond the End

Made a sip of mashroom vodka from brass flask, red wine from boiled leather wineskin and healing solution from green glass bottle.^_^

I wouldn't remove old code for drinking one item potions, because, it good to have possibility for them to be, hmm...
It is easy with healing solution, you drink it and you get healed, also, I have to rework different stats potions, like poisons and buff solutions to become fluids, but it isn't difficult.

Well, alcohol would be different and different potions could spirituous too. 
One or two sips of wine or beer, would give your character nice thoughts, but drinking have of wineskin would waste him, until you don't have alcohol tolerance perk, the same it for strong alcohol, like goblins mashroom vodka or dwarven gunpowder brandy etc. But strong alcohol would be useful for removing pain and intense pain debaff thoughts.

It is not wise to drink a lot, even if you have alcohol tolerance perk:
As you can see, at first, character got boozed perk and later, when got more strong alcohol, gone wasted.
Then, a hangover comes.^_^
