I still unfortunately have some fiat bills, so when I get my fiat paycheck, I keep enough around to pay those, and then convert the rest of it into Monero. And as I said, I pay as many of my bills as I possibly can in Monero. Although, that's not many. Mainly my food and my cell phone bill, and my email service, and search engine.
Things I haven't figured out a good way of doing are anything that requires some sort of ACH transaction. Such as credit card bills, car payments, mortgage payments, etc. If you have to give a debit or credit card, it's easy enough to handle with Monero. But if you have to give a bank routing number and account number, then it becomes difficult.
