working

i m not working for a week, suddenly back to work. it was like i have long time didn't work. my muscle & all fresh were so stress all day long. on top of that, my eye don't seems to coorperate with my brain, it keep close up(due to sleepiness). u know what, i rest about an hour in worker's kongsi. later continue my work with all hard muscle, damn exhausted. almost can't cope with it. leave around 4.30pm, reach home sharp 5.30pm. in between, went to change my oil. my motor's engine start to suck my oil heavily, until the oil content in the engine only can last for a month / less.

any idea how to solve the problem in it? feel free to teach me.
