Online automatic bill pay for all the monthly bills.
Separate account for the money I can blow if I need to.
I TRY to spend the money on things that are tangible, like home improvements that I have put off because they are not 100% emergencies. I try to plan ahead like, the next time I go on a buying spree, it will be for a trip I have thought about during the non-manic or hypomanic times.

For example, I have a trip coming up and I am bringing a certain amount of money and leaving credit cards at home. I have already pre-paid the trip on 1 particular credit card. So that is all I am taking.

It takes a LOT of self-control and I definitely am not perfect.
