Aye Grif up there has it, if the method suggested doesn't work a Vet or even possibly looking for a Breeder, or Herpetologist center, association in your area could assist too, I've had to call a few in my own area just for information and confirmation of what I have, will, and want to do involving My own Pac, just search the net, and make some phone calls, you may have to call long distance depending on the area you live, but you just may find someone close to you that can help you out as well, seek help from any and every avenue, you never know where help will come from till you start asking, and the folks here are notoriously accurate, so relax and follow the steps provided above.

If force feeding becomes needed, which as it seems thus far it is, there are quite a few youtube vids of people doing just that, I had to use the cleaned and sterilized Drivers license / Credit Card applied to the side of his mouth and sliding a cricket down his gullet off the cards smooth surface, I hope you can get you Pac back good n healthy soon, Good luck to you and yer large mouthed friend.
