I am currently on the following medications to treat high blood pressure and and am a pre-diabetic: 1)Metoprolol Tartr @ 25MG 2x day; 2) Clonidine HCL @ 0.2 MG 3x day;  3) Amlodipine Besylate @ 5 MG 1x day;  4) Hydralazine @ 50 MG 2x day;  5) Niaspan ER @ 500 MG 1x day.  Is there anything about my medical condition(s) and/or medications that could affect a blood/alcahol reading in a blood test?
