Is Vampirism Actually Useful for Stealthy Archers?

Question

I am running my own Sneaky Archer using Conjuration to support myself. Yesterday I started to think about contracting vampirism, but I have some questions about it.

** Spoiler Alert: **

1 - I know you can't contract werewolf disease more than once ( the only way to become infected is questing with the Companions ), but how about Vampirism, can I get infected, heal myself and get infected again ?

2 - How long ( in game hours/days ) does it takes for each stage to end and start a new (higher) one ?

3 - You only have penalties once you reach Stage 4 of Vampirism, right ?

4 - Is the 25 % + Stealth Benefit that useful in my case ?

Thanks in advance. :)

Answer 1

1. Yes you can contract it multiple times
2. You advance a stage each in-game day you do not feed.
3. No, you have penalties at all stages, they are just extreme at the fourth stage.
4. I would say no but this may just be my personal bent on the situation.

Unless its for RP reasons, the penalties (specifically the regeneration issues when out during the day) make this status not worth it in my opinion. It would seem a better use of your items/blessings to just directly improve your stealth instead of having to try and compensate for this manner of doing so.
