I am a 22-year-old male who, last time I weighed myself, weighted 130 pounds. I started taking mirtazapine for depression and anxiety about three months ago and didn't really notice any weight gain. However, last weekend was my fraternity's crossing of the new pledge class, and the morning of I noticed I had to lie down and suck in to get my dress pants on. In one of the pictures of the event itself I have an unmistakable gut. I weighed myself today and sat around 153. How long does this go on for? Formal's in two weeks and I kind of like fitting into my clothes and getting laid. How long does this continue for???
