I need to fast (water only) for 12 hours prior to my lipid/cholesterol test. Quest Diagnostics (in where-I-live) is open on Sat at 8am. It says that I could get there at 8:30am. So, I'll stop eating at 8:30pm on Friday and skip breakfast and take light rail on Sat morning. Please remind me not to eat anything after 8:30pm on Friday.
