wow. i am a 36 year old female that started taking 50mg of toprol about 1 month ago for frequent pvc's. all these side effects i am reading about are just blowing me away. i have several...foggy, tired, difficulty falling asleep, muscle aches, weakness, tingly legs, weight gain, depression, nightmares, swollen ankles, hopeless feeling, decreased sex drive, cold hands and feet, leg and foot cramping.... NONE of which i had before. THIS MEDICATION IS EVIL!!!!!!!!!!!!!!!!!!!!!!!!!! i will be weening myself off of it starting NOW!!!! i would much rather feel my heart beating funny than feel like this.
