Yes, Coreg sure has side effects when withdrawing from it! I feel like I went thru hell for weeks! I guess it was only 3 weeks until the internal shaking stopped! I felt awful! My neck felt like I was being strangled! My upper arms/shoulder/neck hurt! My legs were weak..I was weak! My hands are still trembling! I took Xanax before when I was getting a repressed memory. Oh my! That is a MAJOR TRANQUILIZER! I stopped that as soon as I could and advise others to stay away from it! Julie, I am so sorry you have to go threw this! Maybe after its all out of our systems..we will feel great! I hope so!
