I am limiting myself to carrying 5 potions at a time with the character I am about to create - a light armor sword and boarder who uses archery and resot

I was wondering how many perks I need to take in restoration? The novice healing spell is incredibly useful to me with the regeneration perk, but I need something for a fast dose of healing. I was wondering what level of spell I need, and how much magicka.

I find "close wounds" the adept spell the most useful, you will need level 50 restoration to half the cost of it.
