are you using a uth or light? i was using just a light and my bp started fasting for about 5-6 months off and on. a herpetologists friend told me that she might have had trouble digesting her last meal, and he made me an uth (to boost belly heat). it worked wonders. i waited about a week and a half/two weeks to feed and she constricted in less then one minute and ate in less then three. if there are any other options try them, force feeding should be a last resort. and if you do have to force feed, talk to a herp vet as this method of feeding is obviously very stressful to both animal and owner. all the best, there are a lot of experienced people here who are more than happy to help.
