The one thing I learnt from my IMC training and rating was that it was way too limited to be of any real use and my confidence to use it was affected by my own percieved limitations of the rating.
Before the school took your money for the training, they should have told you that you will almost certainly need more than 15hrs, will need access to a suitably equipped aircraft to fly afterwards, and will need to keep current perhaps to 20-30hrs/year.
In practice, almost nobody is told these things up front...
You need the above things to fly in IMC, no matter whether you do the IMCR or an IR.
