drive back on: drive someone back on something: to force someone to tap reserves of something. e.g. The hard times drove them back on their life savings. e.g. The challenges of being a corporate executive drove her back on all her personal resources.
These is the definition I found on the internet. But the explanation makes me more confused. Could you tell me what "tap reserves" is?
