I was prescribed Silenor 6 mg the first week of August 2015. It's now the last week in September. I haven't changed my diet and/or excercise. I'm disappointed in noticing that I've gained 10 lbs since adding Silenor to my medication regimen. I would appreciate some honest feedback and answers from the manufacturers, physicians statistics, and some potential patients who have asked this question or concerned if this is a side effect.
