Other than that hot showers (as many as you can stand for as long as you can stand it), advil, OTC sleep aid - maybe like benadryl
. I know it sounds hard, but get up, get out and
take a walk. Exercise, especially at day 4, is realllllly important. I cannot stress enough how this can really help with the aches, anxiety and ancy feelings.. walk around the block, or run if you can.. helps release some very much needed endorphins and eat and drink healthy - gatorade, fruits.. Other than that..
