Look, I don't even use potions at all because ur right they spoil the game and u can barely get them at all. My advice - save up the potions for something special.
The thing I do is just run away when u get hurt, then run back in again. Yes, that would make this the most boring game of all time - but there are not really enough potions anyway and it's not my fault I did not make the game. The potions are weak as well and they barely recover health and u can't use too many at the same time.
Basically, I used to run in, get hurt, then wait out of sight, whilst reading a book from the Dragon Age game world series.
I wish I had the infinite time to fix every game lol.
All the best.
