I have also experienced 3 days of significant clarity and alertness with Nicotinamide Riboside (275mg upon waking) + Pterostilbene (150mg with breakfast), only to crash on day 4. I continued taking it for 10 days, with no relief.
Aside from my enthusiasm for anti-aging, I also suffer from excessive daytime sleepiness, its source undiagnosed. No matter how long I sleep through the night (can be even 12 hours), I can never seem to get enough, waking up groggy and desperate to go back to bed. I get sleepiness "attacks" during the day where I can't function and have to nap. This is periodical (some weeks, months are better than others). Note that this is not tiredness. I exercise regularly and don't feel unenergized. Just sleepy. I fight it with the aid of Ritalin, when needed (most days, several doses throughout the day), Modafinil, sometimes caffeine pills (cups of coffee don't provide nearly the amounts I require). I experimented with many other supplements and medication, to no avail.
During those 3 days of positive NR influence, the benefits were unmistakable. I was genuinely put off by going back to bed to sleep, and my motivation to be active was at an amazing high. However, when day 4 came by, I was sleepy even more than usual! I hoped it'll subside as my body gets used to the substance, or maybe it was just a couple of rough days, but no. I am now off it completely for 2 days, still feeling incredibly sleepy all day long (even while being ON Ritalin). In a weird way, this dramatic shift leaves me optimistic because NR must be something special, if I just get it right.
In the post above, the author then tried to stop and went back on a reduced dosage, finding that to be the solution. I'm going to try halving the dose when I get back on it tomorrow.
In the thread, someone raised the theory that this crash was due to undermethylation, which I'm going to test out (with Methylfolate and Methylcobalamin). I've also seen somewhere else mentioning the importance of B-vitamin balance when taking NR.
Has anyone else had a similar experience?
Does anyone have an alternative theory/suggestion to the peculiar effect?
