I know how you feel , the first time my BP went off feed I got kinda nervous , but after reading about how common it is I didn't worry about it.
everyone says as long as he's not losing weight dramatically , he'll probably start feeding again.
when it happened to me the first time , it was kind of a pain since I didn't have anywhere to put the rat, so I had to set up another tank in case he didn't want it, and wait another week and try again.
now, its not so much of a hassle, since I have everything set up . if he doesn't eat I just feed the rat to my boa, or put him back into the rat tank for another week.
