So my biggest annoyance so far is my body tempature bouncing all over! One second I'm so cold I'm shaky (it is chilly here) then I get up to make a cup of coco and before I could even sip it I'm super hot! I don't remember ever having such hot flashes so early. Had the same problem last night. I have a huge research paper due at 8am and I just can't concentrate. Anyone have hot flashes at 4weeks?
