You only need to fast before blood work if you are having a fasting blood glucose blood test. Not each blood drawing will require you to fast. If you are required to fast, you may still drink water before your blood work.

Can you have tea sweetened with splenda before a fasting blood test?
Typically when fasting you can have BLACK coffee or plain tea (nothing added, no splenda). This is only if you really have to have the it or forget. Fasting means no food or liquid consumption(water is just fine), including NO gum or candy. By the way you can brush your teeth just don't swallow it. Water is good! It make it easier to draw your blood, since your blood is mostly water. Usually you can still take your meds, unless the doctor tells you not to take them. I have been a Lab Tech/phlebotomist for 3 yrs. I give fasting instruction many times every day. And I turn people away for adding splenda.
