Hi, my husband thought he was suffering from depression, the doctor put him on paxil, he's been on it for about 4 months now, he thought it was working, but now he says he doesn't even think its depression its more anxiety. He grinds his teeth at night and for the kongest time has never slept a full night, he is up like every hour! what do you guys think it is and what meds can he take for anxiety, please help!
