Question about alcohol Withdraw?

I'm 24 Ive been drinking every night pretty heavily Like half a wine box the 4 wine bottle ones a night for about a year maybe two I stopped drinking Ive been clean for a week now How long until the alcohol is out and i feel normal again? Ive noticed that i don't shake as often as i used too but now the headaches and just feeling down is starting too kick in. Any advice thanks
