Listen to Adam and the rest of the guys ... Your snake needs to heat his belly to facilitate digesting his food. That is why he re-arranged things in his terrarium, and is laying on his hot spot. You probably won't see much movement from him for 48 hours or so while he rests. You know how it is, after you totally cash a big prime rib, a baked potyato and 7 or 8 Guinness ... you lean back, unbuckle your belt and get real tired ... that is how it is with snakes too, only they rest a little longer because they digest their food slower than you do, and htey need heat to aid in the process.

Remember not to handle the snake for two or even three days after it eats (to avoid stressing him out, which will lead to him re-gurgitating his food) and make sure his tems. and humidity are optimal and consistant and you and your snake will be alright

I am glad to hear you had a good feeding session, I did tonight as well, so now Allister is setling down and relaxing ... you'll be fine as long as you are patient, watchful and condsiderate.
