Gimli, trust me, we have all done it at one time or another. I try to take mine at a certain time each day, yet if I get distracted will wonder, did I, or didn't I???? I know one day I finally counted them about 4 p.m. and knew I forgot to take one, but just waited till the next morning, no problem. As long as your numbers are 126/73, I'm sure U will be just fine. I don't think they come out of your system that fast, so relax and enjoy your evening......
