I have been on 15mg mirtrazapine for around 3 months. I am starting to feel more anxious than I did. I am wondering if upping to 30mg would improve my negative thoughts. I have been here before a couple of times in the past & been on citalopram & venlafaxine at different times. I would not consider my situation as desperate but I need to improve my mood. I know everyone reacts differently so hence my question as regards to upping to 30mg. Will I lose the sedative effects of 15mg? Also will unpleasant side effects kick in by upping to 30mg?
