I've started taking the sodium cromolyn. I was surprised to find the effect feels somewhat similar to niacin. I have a warm sunburnt feeling on my upper back which I assume is a flush. It's not as intense as Niacin though. From my reading nobody really knows why it works as a mast cell stabilizer. I have used high doses of niacin in the past to cause a large flush before an O which I assume works because the mast cells are pre-activated and drained. I'm wondering if taking sodium cromolyn daily does the same thing and just keeps the mast cells empty? Any thoughts? I'm unable to take the full dosage since it makes me feel a bit woozy but I will try to work up to full daily dosage.
