Yes. This evening at 6PM I took my usual medicine of 100 mg. labetalol, 325mg of aspirin, 3.5 mg of warfarin, and 40 mg of lisinopril. Tonight, about 45 minutes ago I went to take my night pills and forgetting that today was Thursday, I took my Friday 6PM pills the only thing different in the Friday pills was 2.5 warfarin. I alternate 2.5 and 3.5.
