I copied this from the Witcher boards since this is really a big issue for me. I hated the short time of potions in the retail version and I still hate it and want to change it. What do I need to do?

Preferably 15 or 20 minutes without alchemy tree points spent. I hate it that you can't roam in the forest that long without constantly stopping to gulp potions.

There was a mod for that if I remember correctly. Look for it on the official forums, and check if it still works with EE.
