Thanks for the suggestion Vita-man. I might try NHG B too. I have never used that one yet (I've used session A but not B), so I'll give it a try.

Scooter, the way I see it, New Option Generator is for when you have a specific decision or problem with several options and you need to either choose a way forward or else generate a new option (eg thinking outside the square if necessary).

New History session A is for when there is a specific situation, interaction, choice, or something else that has happened in the past which you want to be able to forgot or move past without regrets etc.

Session B I think is for reviewing your day and/or setting up a successful mindset for the day to come.
