So sorry to hear about your mom! The
morphine pump is a good pain killer.She should actually build somewhat of a tolerence to whatever she is taking and when she does she won't sleep near as much.At least right now her pain is under control and
oxycodone when taken orally is about one and half times stronger than morphine.
Another drug that is being used more and more for terminal patients is
methadone.It's a great pain killer and it doesn't leave the patient all loopy.Hope this helps,my thoughts are with you....Dave
