I'm at a loss..is this "normal?" (a bit long)

I'm hoping someone can help me here. I began a parasite cleanse-not containing Wormwood -3.5 weeks ago. The first week was hell with terrible sinus, ear and eye pressure, along with brain fog. The 2nd week I felt great-energetic, no pain, no fog. Doing intense workouts. Third week, ugh, I feel like crap. On and off anxiety, nausea, fatigue, weak. I made it through only 2 workouts last week, and I'm typically 5-6 per week. A week ago, I became constipated, and after 4 days, finally began going again after using Yerba mate and triphala. I'm still only going about twice a day. Last week I also began taking some liver detox herbs, as I was told they'd help with some of the die-off symptoms. My eyes got really bloodshot, didn't feel right. I did an eye flush and that helped quite a bit.
I'm 43, and have been in great physical condition until things picked up this summer. 3 years ago, after 2 cycles of cypro for an inner ear infection, I began having rapid heart rates (PSVT.) Had complete workups, nothing was wrong. Hooked up with a holistic nutritionist, who changed my diet-which is pretty close to the candida diet. Also found out I had low Mg. Supplemented with that, and between that and diet change, things got better. They started up again this year, after another cycle of anti-biotics in the spring. Gained 14 lbs, brain fog, etc. Finally diagnosed with candida. While treating that, I took a trip to Costa Rica in July. (Avid sushi eater as well!) Needless to say, things got worse when I was there, but I managed to get the weight off with anti-candida supps, diet, and workouts. Things began getting worse again, and I discovered this forum, and feel like parasites could be exacerbating the candida, vice versa. I am seeing some crazy things in my toilet after I go, but not sure if I've seen any actual worms coming out.
Am I doing too much at one time? I'm finally sleeping great, through the night, but this shaky feeling and weak/fatigue during the day is awful. Anyone have any clues? I went to a naturopath, but he's freaking clueless. I'm in a state/area where there aren't options for natural docs. I also had a total physical workup this Sept, bloodwork came out great, but low on Vit D (supp there also.) This sucks and I'm getting discouraged.
