Anyone having really odd side effects? Not the normal stuff like dizziness of fatigue (comes from lowering the BP). I'm talking sudden onset shaking chills. I have boughts were I cannot get warm and I'm shivering from head to toe. I don't have a fever or anything. DH felt my upper arm and asked if I'd run to the garage for something. It isn't clamy either.Last night was the worst because after walkng all over Chicago the whole day, we got home and I went to bed. Woke up feeling like ice water in my veins, reached for an extra blanket and endd up with twin hamstring charlie horses. I couldn't move. Poor DH had to come to my rescue with the spare blanket. Kinda funny, in retrospect, but alarming when it happens. Since then it has happened 2 more times, though, thankfully, without the muscle cramping.
