I am about 10 hours into my current playthrough and every time I try to use radaway the game completely freezes and I have to restart the 360. I haven't tried using a doctor to cure my radiation sickness but If I can't cure it with radaway then doing HH, DM and LR will become very tedious/near undo-able.

Having to cut my losses and restart isn't too bad having only played for 10 hours but if anyone knows of a possible workaround it would be much appreciated.
