There is no hard core yes and no to your question. If your are really afraid then see a doctor. I am not a doctor. I can't tell you yes or no. I doubt a doctor can tell you yes or no. Everyone is different. Some have major withdrawals while others have almost none.
If you have gone 2/3 days with no alcohol and have had no physical symptoms then I don't see what is keeping you from stopping for 2/3 days again. Are you worried about day four?
