@73monte - Ativan can be pretty addictive. Same with other benzodiazepines. I save that for once in a blue moon use. One thing that has been shown to work quite well for health anxiety is Cognitive Behavioral Therapy— a practical, relatively short term therapy. If your wife is motivated to beat the health anxiety, that might be the best approach.
I really don't think my wife will opt for any meds again. She just didn't have a good experience with anything that she tried.
A previous poster did suggest CBT, and listed a webite that I've shown my Wife. She's quite interested in checking that all out. Thanks for the reassurance of that appoach though.
