We are so sleepy. We can't afford to fix our heating unit. Sometimes it comes on and sometimes it does not. We have to get up at all hours if we hearing it running and the flame does ot ignite. We just keep cutting it on and off until the flame lights. Help us please

Best help for you is to tell you to call for service and have them do a test for a damaged or defective heat exchanger. CO poisoning can cause you to feel sleepy also.
