He must have confidence in your assessment of how you are feeling. Maybe you should try the higher dose--you can always cut back again if the side effects are too much or it doesn't help more or you get to feeling better and want to see if you can maintain that on the lower dose. How wonderful--you are in the driver's seat and have been given license to make your own choice! If it were me, I'd probably try the higher dose at least for a month or two and see how it goes.
