Very new to the sub and the game, so here's a noob question. I'm currently at level 6 and I've been merrily exploring the wilderness while doing main and side quests with Lydia, helping those who need help and killing those who need to be killed.  I got up from a nap at my house in Whiterun and a message appeared on screen that I'm feeling fatigued after sleeping.  Similar messages popped up for a few in-game days, now I get a red flash at dawn and it says the sun boils my blood.  It wasn't too hard to figure out I'm turning into a vampire.

I'm currently scrambling to cure it, I purchased a black soul gem from Falion and a spell book for capturing souls.  During the day vamirism is a serious handicap, however at night I'm far more powerful.  Browsing this sub's archive, it's apparent that becoming a vampire might be needed for achievements, even desirable in some contexts.

Any insight or advice?
