1200-1600 is not excessive for the average person. But, I can't say for sure since you are on medicines. The vegetarian diet shouldn't make any difference in your Sodium needs. The RDA is 2400mg. I shoot for 1500-2500mg...and usually end up around 1800mg. My Blood Pressure [the top number] dropped 20+ points after going LC and another 10 points when I started watching my Sodium intake.
