I am a grieving mother suffering with "Complex Grief" for almost 4 years since I lost my son. The PTSD associated with this is profound and frequent. I have had a terrible reaction to a prior medication. I have had trouble gaining weight, as I am not often very hungry. The first medication made me lose a couple of pounds a week. It got to the point where I was just barely 100 lbs. and I am 5 foot 7 inches. I am very concerned that this medication may cause weight loss. Has anyone had any issues with weight. Because my weight was so low at that time, my family doctor considered sending me to the hospital, as she was concerned about my organs shutting down. I'm just at 108 pounds right now as it is harder to gain weight than to lose weight. Thanks for any feedback on this issue.
