Your'e an Orc Warrior............do you use the Berserk spell?
It's kick-*** it boosts all of you combat skills/attributes up aolt but later your fatigue will drop massivly that may be why you keep getting knocked out.
(to knock out/down NPCs use a blunt weapon or your fists/claws and swing them HARD)
The flowers you need to find are all found between Balmora and Hla Oad and the Mushrooms are all found in Seyda Neen...
