Approx. 2 days before my period I wake up with the most horrendous headache/feeling sick/wanting to be sick/needing the loo - it lasts all day. Only by going to bed, which, given the fact I work full time and am a mum, is not possible during the day will it go. It only lasts the one day but boy-o-boy, it knocks me for 6. Does anyone have a miracle cure - I will try anything!
