I have some fairly stark opinions on these situations, it sounds likes you've really been going to town on the anti fluke front. But can I ask, do you feel that much better? Will you stay feeling better if you stopped treatment?
Cards on the table, I believe a lot of the fatigue related illness are down to latent grain allergies. But heres the thing, you could have one of a whole host of illness causing your problems, flukes may be present but maybe not the cause. Liver Flushing helps aswell with a whole load of ills, because quite literally the process draws a lot of toxins out of the body.
Sorry if this comes across as me shooting you down, but it sounds like you are putting yourself through hell, possibly without gain.
