I understand you, Salah. I am also confused by the 'recovery' thing.

Mykwyner: You effect a recovery with a few drinks, means that the drinks are effective for your recovery, right? The question is: recovery from what? As far as I know, drinking only makes things worse.

Could these examples help?

* Effect as a verb means "to bring about" or "to effect a change."

El Nino is effected by (caused by) global warming.

* When you affect something, you have an effect on it.

Air pollution affects (has an effect on) the global climate. It is a pretty effective (not affective) means of damaging our environment.
