They often repeat on me too (the dung-like whiff of it really does turn you), and can take some time to go down (even a couple of hours later). I also suspect you get a double-hit of the bitterness in your mouth when it gets absorbed in the bloodstream.
Try it. I was having the same problems as you (vomiting as well) and found the vile stuff much more bearable over the last few rounds that I had been putting them in gelatin caps. Haven't vomited since. When I also couldn't bear the 3x doses over 3 days so went for 2x over 5 days instead.
