I am doing the B complex and C supplements at the same time, as you are doing. Last night I took a 2nd round and barely noticed any flushing. I had no flushing with my first round today. I think I may be adjusting to this very rapidly.

Of note: I took a long, brisk walk yesterday and felt wonderful afterwards. That was not unusual a while back, but lately I had not been getting that endorphin thing from simply walking. I guess it wasn't really working out hard enough for it. It was nice to feel nice after that walk.

Last night I slept amazingly well. My Garmin fitness tracker measures movement and estimates the time of "deep sleep" during the night. If I get less than 3 hours of deep sleep I normally feel it the next day. I feel well rested when I get 4 to 5 hours of "deep sleep". I rarely get more than that. But last night my Garmin says I got more than 6 hours of deep sleep. It will be interesting to see if this related to the Niacin. If so, I should see a trend of longer sleep develop.

Again - the current plan is to work up to 1g of niacin daily and then hold steady for a while. I read up on it and this seems like it might be beneficial for me. I was metabolically ill for decades. I like the 'cleansing' ideas behind fasting for that reason. Niacin therapy may have similar cleansing benefits and might even work well with fasting. It may be hard to measure, but I feel good. So I will keep working on my N=1 ... ME.
