The ideal learning rate for most people is minimum 2 lessons per week and indeed you are violating the basic learning rate principle the way you are presently doing it. You may be a normal learner but you are throwing water on it with all those gaps. 3 lessons per week is better, more is overkill for most people. If you take less than 2 lessons a week you are barely retaining what you had, if not losing it. There is a momentum that gets established not only for you but for your instructor who may forget where your skills are.

There are several "pilot mills" offering rapid PPL training, I suggest you save up some cash and buy one of those courses. AllATPs, Sheebles, American Flyers, there are a bunch of these schools. The general idea is you go where they are for a week or two and leave your other life behind. When I have had conflicts in the past with long job hours and my flight training, I have made use of fast courses. The way to do it is to save up the money while you study using a self administered program for the written exam. Take the written, then schedule your flight work during your vacation. These courses are best viewed as concentrated finishing courses, so you should go to it up on your knowledge and ready to knock it out quickly. Showing up cool will make you end up having to buy extra hours at a steep rate.
