Hello I looked around and didnt seem this posted but if its a repost please take it down. This is going to sound like im full of shit but if you just try it you will see it works. In the game after you are hurt and need to drink to regain health out of combat just hold alt + F4. I know, i know oldest troll in the books but just try it. It will fill your health bar without taking anything to drink. Sometimes its very fast sometimes its slower. Make sure to actually hold it, not just press it. I was flabargasted when i saw it actually worked. If I am lying and it logs you out feel free to ban me just thought id share.
Edit: For some strange reason if it isnt healing you fast you can run forward while holding down the buttons and if you stop for a second it will fill up super quick.
