I am 20, and have been on Toprol for about 10 months. I have the ichiest, most irritated legs in the world and am always freezing! I can put 15 layers on and still shiver. And sleep!! I can't get enough, I can't wake up in the morning, I sleep through my classes and I fall asleep on my friends couches when I hang out with them! Plus, And may I remind you, I'm 20, I have NO sex drive what-so-ever! I didn't have these problems before starting Toprol. Granted I am a college student and sleep has always been an issue, but never to this extreme.
