You need to get wormwood and take that..I am not sure where it is found but, that is what it takes...It costs Linden though to get the Wormwood potion though...And you will need someone I am told to buy your soul back for you...I have a friend in here that tells me his was taken a long time ago and he sees no difference in the game play...But, if you get your soul back get yourself a Garlic necklace and activate it. And do not take it off or deactivate it ever...
