ok, i meant cure vampirism potions,
correct, the self brew disease cure potion will only cure the disease before you become a vampire
and cyrus, if you are ok with cheating, open the console and type in coc testinghall exactly like that and you will go to the testing hall, go to one of the rooms that says wooden door to(blank) it doesnt actually say blank, it just stops after door to, then there will be a room with crates, one will say all potions and ingredients, there will be a cure vampirism potion in that crate
now...i must use cheat...it is shame...but it's last way...
thanks erlltheskwerl and every one helped me..
