IMO he may have been misdiagnosed. One visit to the p-doc isn't enough. Based on his mood swings, he may be bipolar. That's a different medication - lithium or Depakote. These tend to temper moods and are well tolerated without any goofy side effects like jabbering on and on as you described. Also his behavior on line and his quick judgement to leave for "anywhere and nowhere" is also a hallmark of BP (risky decision making, the need to flee).

If he's willing to do so, perhaps it would be a good idea to go back to the p-doc for some mid term monitoring. No one has anything to lose. In my case, I was exhibiting the same behavior (alcohol, yelling, etc) and my family literally *forced* me to see a psychiatrist. I probably would have lost my marriage if I didn't get some help. Originally, my p-doc prescribed a thin dose of lorazepam to chill me out but we can't take that long term. I think I may have seen him six or seven times before he finally came to a conclusion of bipolar based on what I told him about my moods, my behavior, and how it all affected my family. He knew something was up, he just wasn't willing to jump at it on Day 1.

Personally, I think the Zoloft call was way too quick. It sounds like all it did was agitate him more.
