Doea you husband rinse with water baking soda and salt mixture? If not he should be doing that several times per day, it will help. Its a quart or water and 2 teaspoons baking soda, and 2 teaspoons salt (the salt can be omitted or cut back if it bothers him).

Please remember, most of the people responding to your posts have gone thru this as patients. Its a very difficult thing to go thru but it can be done. Some OC patients and their caregivers too have needed anti depressants to help them cope.

One thing I have found most helpful is attitude, it will make things so much easier to think of the good. I have had OC twice within a year and have been left with some pretty bad long term after effects which may be permanent. Your husband is very fortunate to have had a such a wonderful caring caregiver. He is also very fortunate to have won his battle with OC. Congrats on the clear PET scan. It will get better in time. Patience is key as recovery will take quite a long time.
