I have read that due to coconut oil's anti-microbial action, people may experience a microbial "die-off" when first taking the oil. The microbes release toxins into the body as they die, making you feel like crap during the process.

Although I didn't experience that with coconut oil, I have gone through the "die-off" blues when I took antifungal medication some years back. I sympathize, and I encourage you to reduce your dose to 1 Tb./day for a week, and increase by 1 Tb./day at weekly intervals until you get to 3.5 Tb. Stay there for a couple of weeks, then go back to 2 Tb./day, and see if you notice any difference.
