Mad Man

In the past I occasionally drank. Nowadays I need some beers every day. Until now I have achieved to avoid drinking whisky. It is hard to let time goes by. Another cloudy day. How many cloudy days can a little person endure? 
I think it is the government who makes the free days are raining and cold . It is for productivity. More money for the wealthy people.
How do you say 'desquiciado' in English?
I guess something related to madness. Mad man?
