Dan I'm glad to hear that you feel well enough to reduce the mirtazapine. I am afraid that I dont know why the drug is more sedating in the lower doses although it is a well know fact. Maybe it is to do with way our bodies absorb the drug or break it down. I have only found the benefits of the sedation when I first started the drug. As far as the munchies are concerned I would try to eat some complex carbs such as pasta or rice at mealtimes so that you will feel fuller for longer. Try not to eat after 9pm at night and hide the biscuits or do not have them in the house. As you may know another side effect is a craving for sweet things. Are you reducing with a view to coming off the mirtazapine? This problem then should resolve itself on its own. Best wishes EJ.
