I actually didn't take any more doses yesterday nor this morning. I took a 12 drop dose about an hour ago and I am 100% fine...absolutely 0 nasea. I really do believe it became so strong because I let it sit out so long. Tonight I only let it activate for 6 - 7 minutes and it was much less intense. Also, by comparing it to Silverfox's pictures, it was closer to the 10 ppm pic than the 100ppm pic. I think I will grandually increase dose until I can tolerate 15-18 drops....I will also not let it activate for more than 8 minutes from now on.
