Hi Jen,I did use morphine to reduce my pain for quite some time. First I took it orally and then I had the IV pump during my 3 week stay in the hospital during treatment. I guess it was effective on my pain problem because I didn't feel any real pain during treatment. But it caused me great problem of constipation and skin allergy. I had to take antibiotics for 3 days to cure my allergy. I didn't experience any delusion or paranoia you mentioned. If you have sleeping problem, maybe sleeping pills can help you because I have been on these for over a year to help me sleep. You may also need some psychiatric counselling if you have negative thoughts. Just some sharing.
Karen.
