Can withdraw suddenly come on despite not having symptoms after 2 days?

Since lockdown, I’ve been a fairly heavg daily drinker. I’ve good two days without quite often, but never further. When I do I feel great, no withdrawal. I am once again on day. I feel great, i intend on this being at least a month.
 
From what ive read day 3 is when the deadly symptoms can come. Can I do from no symptoms to instant death or no symptoms to deadly symptoms quicker than I can do something about?
 
I think I’m just lucky and have no symptoms. But worried I could quickly be proven wrong.
