How Can I Prevent Myself From Overdrawing My Account?

I forgot about an automatic payment which wiped out my checking account two days before my paycheck came in, and in that void I swiped my debit card five times which resulted in five overdraft fees of $35 each. Of course I had plenty of money in my savings account, but since I don’t sign into my bank account every day (should I be doing this?), I didn’t realize in time to transfer the money.
