I have been taking paxil for about a month. The first couple days I first started taking it I had a panic attack and then a few hours later a felt very good. Then eventually my moods were just more calm, relaxed and stable. This past week I have been experiencing some bad symptoms. I have been having night terrors, I twitch and have tremors in the day time, I feel extreme fatigue, anxiety, muscle weakness and stiff. I have this weird sensation throughout my body. Is this normal for antidepressants? I also drink kratom daily.
