If you read medical literature documenting seizures and withdrawals. It's extremely rare for seizures to begin after 48 hours and DT's begin within the first 3 days in almost all cases. This usually occurs after years of very very heavy drinking in most cases over 10 units per day.
However, everyone is different, so my advice is to see your doctor and let him tell you this to relieve some of the anxiety that you brought upon yourself by Googling.
