Married couple going into USAF. I have guaranteed job as an Air Traffic Controller. Any Advice?

My husband are both in the DEP for the USAF for just a couple more months. I am excited to go but a little at a loss for what to expect. I know that being an air traffic controller is (from what I've heard and read) a very stressful and demanding job. Not only that, I heard that there is a very high "wash out" rate for the Air Traffic Control tech school. If this is still true, why and how(other than just "it's difficult")? I am anxious to hear from anyone with any personal experience with this career in the Air Force. I would also like to hear any tips on how to keep a marriage a happy one (no current problems with my husband) with a job that could be very stressful (or for a couple in which both are in the Air Force). I know that patience and loving kindness is golden but any other hints or advice would be much appreciated. Thank you so much for any input and advice! =D
