Yeah eikthyr, stamina potions and maybe raise some terrain for natural barriers. Another thing one can try is putting Tasty Mead on the hotbar, while it's not a particularly good mead, it ends up being a stand in for a stamina potion, so while one is on cool down you can use those until your cooldown is over. they themselves only have a cooldown of 10 seconds.
