"I was put on the Remeron initailly for insomnia. It caused me to gain a little weight but I only weighed about 95 lbs. so that was a plus for me. I took it for about 7 years. Then the sleep got worse and Ambien was added. I have been diagnosed with anxiety, stress, and panic disorder as well as fibromyalgia. It finally got to a point where nothing was working. Two sleep specialists later, I am just dealing. I had to quit work because of the inability to sleep and function in my job. I am on Seroquel for sleep which has caused me to gain about 25 lbs unfortunately it has been the only thing that has helped with the sleep and the Klonopin. Remeron was great for depression and sleep for about 7 years. I gained very little weight from it and it works."
