The best advise I can give, other than reloading previous game, is to go into the poisoned room. After you get thru it you will find more health potions. If you've found a battlefield key, you can transport there and buy potions and sell some of your stuff. It sounds as if you have tried the room and have been unable to find the lever to turn it off. If so,

SPOILER: The lever is in the southwest corner of room. Hope this helps. Alot of times I need a little help myself. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
