alcohol and low testosterone levels

I have been drinking daily for almost 4 years and now I have low libido and I can’t keep a hard erection I’m trying to stop drinking or at least drink once a week, but I have heard that zinc is good for increasing testosterone levels so I bought now zinc picolinate 50 mg but I have heard taking too much zinc may cause low copper levels, is there any other supplements that can help me to boost my testosterone levels?

is this problem a permanent problem or just go away when I stop drinking? and what about drinking once a week?
