Only just started couch to 5k, now i have lost some weight sicne my last bout of running but yesterday i did week 2 of the couch25k about 10.30am and after coming in i had a shower nice and hot and just couldnt get warm, had a sunday lunch then later in afternoon felt almost like i had the heeby jeebies and had a really long hot bath, gave in and after a lemsip took myself to bed at 8pm, slept solid then woke at 2am freezing and shivery again - i dont have a cold or anyhting and even today at work i felt all cold again i just cant warm up - is this common and how can i counter act it because its run 2 tomorow and i dont feel motivated if its going to make me feel ill. Any advice?
