Olympic2012,
Stress is a major cause of grafts blocking up.
My wife and I separated in Jan this year - this caused me major stress and I started smoking again, I went to the docs to get a script for Champix so I could stop smoking again - the doc would not give them to me because she had me on anti-depressants at the time.
She told me to forget about the smoking for now and get my stress under control - she said stress is worse than all the other body nasties combined, including smoking.
She said to get the stress under control and worry about the smoking later.
If your hubby is causing you to stress out I think that could be the reason for your grafts blocking as fast as they have.
Btw: I did stop smoking again.
