Some AD's can actually make a person WORSE. If she is on the wrong one's she may not realise and she may need a third party to point out to her that she needs to go back and try a different one. It usually tales a couple of months for the AD's to take proper effect and then if one changes you have to be weaned off them, clean for a week or so, and then start on the new ones....which again take a couple of months to get working fully. The weaning off and starting up again period can be really tough.
Also, one should NOT drink whilst on AD's - it could be accentuating your W's problems. Many people also think if they are on AD's they are at greater risk of having their children taken away from them in a custody dispute.
Could your W be Bi-polar?
Honestly mate, Relate have a bad rep when it comes to saving M's.
