Hi, I m under extreme stressors, lost job, dad had stroke, and I ve been out of my apartment for 3 months due to a water issue. I just returned home, really needed to sleep. I took a 50 mg Trazodone about 20 min ago, I m on a T3 and synthroid as I have no thyroid due to cancer surgery 2 years ago. I ve taken it before with no reaction. I just laid down and my heart started racing.
