Your abdomen could be swollen for a number of different reasons. These range from eating too much to pregnancy. Only your doctor will be able to determine the exact cause of your swollen abdomen. Some of the most common causes of abdominal swelling include overeating and gas. Swallowing air as part of a nervous habit or from eating foods that are high in fiber can lead to gas production.
A common guideline is that after each typical drink, you must wait 45 minutes before attempting to drive. If you have another drink, you must add another 45 minutes. You've had a drink and must wait 45 minutes before driving. A quarter hour later, you have another drink. Now you must wait 45 minutes PLUS the 30 minutes left over from the first drink. That's one and a quarter hours before you should drive.
When driving in residential areas you should signal around 30 meters (100 feet) in advance of making a right or left turn. This is assuming there are no other turns on the same side of the road before the turn you intend on taking, else you will need to signal after this turn.
