Thanks for the responces!!
The reason given by the doc to stop taking the Niacin is not very clear or even very scientific. He simply stated that he felt 'I was taking too many combinations'. He asked me to cut out the niacin until my next lipid profile in April after which we would revisit the niacin issue. I got the feeling he did not place much value in niacin therapy.
My liver enzymes were fine and yes 3000mg is a lot of niacin. I took me a couple of weeks to build upto this amount starting at just 200mg/day. By the time I was on 3000mg I had minimal flushing which would last approx 40mins. At the start the flushing was just horid. I thought my whole body was going to spontaniously combust
