"i have been taking 20mg of brintellix daily with mixed results for my general anxiety.  i can go as much as 2 consecutive days anxiety free.  however some days i wake up anxious and then over the course of the day the anxiety will lessen.  also the opposite happens, i wake up with no anxiety and then become anxious over the course of the day.  so far it seems to be somewhat inconsistent.  the best part has been that i have not had any side effects other than some slight constipation.  also currently a generic does not exist so the medication is somewhat expensive."
