I was doing OK using the advice given (thanks everyone) and then, as often happens, as soon as things start to go well I hit an almost phyisical barrier, so that every time I thought about using a paraliminal I found some very good reason not to.
I then decided to use NBG with the goal of always using the paraliminals when I have planned to do it. This seems to be working now, but it is early days (4 days - usually 5 or 6 is when I start to feel resistance).
I did think about anxiety free - but I am not feeling any obvious anxiety - just a deep resistance.
Does anyone think that there is a better solution?
