42yrF, had full hysterectomy 3 years ago. On Atenolol for arythmia and Prozac and Vistaril for anxiety. Live in extreme heat and humid part of the south. The past week, I have been remarkably tired, fatigue, lack of energy, feel like I could sleep all day long and not feel rested. Do any of my medications mixed with the heat, cause these symptoms? What to do? I have a family, 3 children, and a full time job. I have to keep going!
