Your snake does not have the genes associated with wobble. It doesn't sound like they are actually showing the signs of a wobble episode.
I'm not sure what the struggle to eat looked like - some snakes get very excited and flop around a little; some get excited but are very specific about the position they want the food in and they will mess around and reposition a lot; some get excited and swallow in award ways which makes the whole process really awkward. They also don't necessarily swallow a meal quickly.
I wonder if the rodent was a bit too large?
