I lost interest in riding about last August. Only ridden a couple of times since then - it happens to me every few years or so. I'm just starting to get back into it, but I'm still at the stage where I can easily find excuses not to bother. My son is a good one, as he's really into his archery and show jumping, so I can often have to transport him here and there. Sad thing is that none of my kids are particularly into bikes so riding, for them, is a chore.
Moral of the story from past experience is have a bit of time off, but when the opportunity for a ride arises - take it. You might just get your mojo back.
