Update:
It is friday evening and Cody is still with us, not so active today but it was so hot. Now that it has cooled down he is moving around a bit more. I hope he starts eating a bit, he does swallow more often now. Not enough to drink enough water but in 20 minutes he swallowed maybe 7 times, before it woudl take him a hour to swallow once. To me that is a good sign.
