I had to have a blood draw today (10 tubes worth). Never until today did I really have problems with it but they had a hard time drawing my blood. They stuck me twice in the left arm, once in the right, and finished up getting the blood from my left hand. The answer is yes, I have been drinking a lot of water (with lemon juice) and a couple of cups of tea today....well today a couple of cups of tea and a half liter of water (blood draw was at 1:00 and I finished exercising at 11:00 if that could make a difference).
Admittedly this worries me. I' diabetic with kidney problems and I don't want any bad numbers coming out of this blood test, I've worked too hard to get my sugar under control and lose weight....but this really has me worried.
