From what you've described it sounds like you fed the snake way too much. How old is this snake? What are your temps and humidity? What are you using for heat? When is the last time the snake fed successfully?
There can be other reasons for regurges other than a large meal; but a bp should not be hindered in movement after eating a meal. You should wait at least 2 weeks before trying to feed again and feed a smaller than usual prey item. Feed one mouse smaller than what you usually give. Regurging takes its toll on a snakes system so you definitely want to wait 2 weeks.
