U.K. PARURESIS TRUST: Post course confidence and practice

I was going to reply on Johnnys post with these thoughts but thought this might be suitable for a topic in itself.
I was wondering if others have experienced slightly negative effects of reducing your practice levels after a course on confidence levels?

I went on a great beginners course which took me from a 'mild' level (didn't feel like 'mild' to me) to 'very mild' and with confidence levels super high, I thought I could do most situations, and I practiced like crazy for weeks afterwards being overjoyed with my new found ability.
After a few months I started to relax and thought I had it pretty much beat, as it's hard work keeping up those trips to loos etc, and you think you're actually reminding yourself of your fear by continuing the trips, better to just 'accept' you can do it I thought, but then I noticed that when I found myself in very high heirarchy situations - that if you haven't been practicing a lot your 'boo monster' can get to work on you again and it brings the doubts back in, and you can have a slip, which again reduces confidence a little etc.

Has anyone else been in situations like these where they think they've got it beat, then relaxed too much, stopped practicing, only to see the boo monster start to do his work again?

I suppose I'm looking to hear from anyone in this situation who's mastered this cycle of 'niggling doubts' creeping in and how you beat them or controlled this, so please pass on any good tips if you have them

thanks
