Mine didn't eat until the house temp got around 80 degrees. I think it has something to do with the change in the season. I hope yours will eat soon. It can be challenging to remain calm when your snake doesn't eat.
My snake spent the last 5 months roaming his cage....trying to get out. I guess he wanted to go hook up. Has yours done the same?
I'm surprised he didn't lose much weight since he was so active and not eating.
