I know I feel down if I don't get enough people contact. Is there anything you can do to have more people contact? Join some kind of club in order to have more time with people? Are there other people at work who might be feeling similarly so you could hang out with them during lunch breaks and / or after work etc?

I think that MAO's do have withdrawal syndromes associated with their cessation - but Effexor is fairly notorious for particularly severe withdrawal syndromes (in internet chatrooms if not with the manufacturers).
