LOL!!,..yes, I can also relate to that part!
I agree, this seems a little long for it to be only searching out a female, and not eaten this entire time.
However, you did mention it holds it's head back,....does it do this sort of like it's looking straight up, or even almost backwards?, if so, there's a chance it has something that's known as "star-gazing". This is something not commonly seen in colubrids, but can be fairly common in Boa Constrictors. It is alleged that it's caused by an amoeba. High doses of Flagyl(Metronidazole) have been reported to help with this somewhat.
And I think at this point, since you said there are no reptile vets in your area, I would try Flagyl anyway for some other possible stomach pathogens. If you can get your hands on some, it's administered at a dose of 25 to 50 mg/kg. of body weight, repeat in 14 days. I use the higher dose whenever I administer, as it is very well tollerated by snakes, and takes care of a large number of pathogens, including Amoeba invadens. 1/16th of a 250 mg pill will suffice for a 300 gram snake.
This can only help, and it won' hurt the snake at all. But don't attempt to feed for at least a week after final dose, so it can regain it's stomach flora that is crucial to digestion.
