Initially felt depressed, then suffered from severe fatigue, don't sleep as well, and in the last few months have had difficulty getting and maintaining an erection. I can't believe several others have spoken about this very same issue on this site. I never had any issue for 47 years and then suddenly a noticeable difference in the last 3 months. Based on everything I read, I'm getting off this drug, and will try to control via exercise and eating habits. Thanks to everyone for sharing their symptoms.
