Is anyone else having shaking, really cold, body aches all over everytime the meds start to wear off? I'm a week pp, but I've been having this since day 3. About two hours before I can take my next dose of meds I get really cold to the point of shaking and ache all over, then I take the next dose and I'm burning up hot and sweating. It feels like I have a very high fever but it's always normal. I did call my doc but she wasn't worried because of no fever.
