I can see your point. It is hard to question decisions you 'know' are right while manic. I think though that the goal of coping skills is to learn them and practice them while you are balanced. You train yourself to become comfortable with them. You remind yourself over and over to leverage them when you are out of balance. You educate yourself on your symptoms so that you can recognize them and have greater insight into your state the next time it happens.

So for example, you might come up with your own questions and print out a checklist for yourself. You keep it on hand and make it a plan to walk through it every time you make a major decision. You use it when you are balanced, when you are up and when you are down. You make it habitual so it becomes second nature. You might even tell your wife about it so that she can encourage you to use it each time you're making a major decision.

So the goal is implant your mind with the knowing that your your decisions will feel glorious, but you owe it to yourself to think it through anyway. Hopefully, the training sticks and then next time you feel the urge to move forward the insight kicks in and you deploy your coping skills you've trained yourself to use.

This is how we change any behavior really. We recognize the pattern, set an intent for a new pattern, practice and then change the pattern through altered actions. It is hard to do when you're manic, so that's why it becomes critical to do the work and practice now while you're able to reflect and strategize properly.

This is of course just how I'm going about this. There are a number of ways and I'm sure the wise folks here have good alternatives for consideration.
