I think I might know where you are coming from:
My urge to dress never really goes away but it will get stronger and weaker based on many factors.
I can almost predict "strong" urges just based on those factors; and at times I feels like I have a cycle.
In my case I feel its just the way I schedule my time and circumstances
I don't think its a mental or physical cycle; just a routine or pattern Ill fall into.
In general I will dress every few weeks;
If I miss a few sessions a Pink fog may blow in.
If I dress too much it feels like "work" or I feel a little guilty about neglecting other things ect.
So I have a pattern or cycle where I dress every few weeks.
