I cycle using T, I discovered this help immensely when I ran out many years ago. As I find I have much the same situation, where I'm good for long periods of time, then trend down. A brief rest period of not using the T cream, say 4 to 10 days, seems to fix all. I just came off such a cycle, as I ran out of cream and stretched the last bit of it out, so my levels declined slowly. It was only about 3 days without, but a nice decline on my way there. A week after restarting, I'm back to fighting form.
