Hello list, I'm supposed to get my blood tested tomorrow since I am taking Tasmar, but took Tylenol this afternoon. Seems now like I remember the Tasmar drug rep speaking to our support group to the effect that Tylenol can not be taken prior to a blood test as it will show up as a liver problem. Does anyone know if this is true or not? And if true, how long before I can have my blood tested? Thanks, Walter
