Eagle,
I agree that you should be on combination chelation. Your experience indicates that the side effects of each chelator make it difficult to maintain full and regular doing. A combination would allow you to take a smaller dose of each, while still getting more chelation than you currently are. For Asunra, split dosing does help, as does making sure your hydration is always good. This holds for kelfer, too. Hydration is extremely important. Milk thistle can also be very helpful in keeping the LFT's down. And make sure you get tested in the morning, the earlier the better, as activity causes the levels to rise and appear higher than they really are.
