Should I be worried

So I’m on day 4 of being sober from alcohol, and so far I think it’s going really well. So basically I started drinking in April and ever since then I started drinking a ton. Didn’t think I had a problem but now I’m starting to realize. The past 2-3 weeks I’ve been taking 3 day breaks and everytime I did nothing really happened besides some insomnia. Should I be worried now that I’m on day 4, because I really don’t want to have any seizures. Also the amount I was doing I was finishing a handle of Tito’s in around 3 days.
