Hello again, dear friends. I started Freddd's protocol Oct. 13th, and got some excellent help. Background info here, first post: http://forums.phoenixrising.me/index.php?threads/questions-after-3-weeks-on-freddds-protocol.33580/. I'm still in the hiccupy, roller coaster period @sueami described on that thread. The bottom of my roller coaster seems to be a lot of ammonia brain, and now I have the 23andme results to prove it. I get the other end, too (my brain in overdrive), and I am suspecting high glutamate. Part of the ammonia problem: NOS2 rs2274894 TT = +/+ NOS2 rs2248814 AA = +/+ NOS2 rs3729508 TT = +/+Impaired glutamate-GABA conversion: GAD1 rs12185692 AA = +/+And low phosphorylcholine: PEMT r27946 TT = +/+ I'm confused as to how to get a handle on the ammonia problem. Re methylation, I ramped up to 3 doses per day: 1000 mcg meB12 + 2500 mcg AdoB12 along with 3.5 - 5 mg/day of methylfolate, plus potassium, plus various co-factors.Then my B12 oils arrived from Australia, and 2 days ago I switched over to the oils, but I have no clue how to compare doses; I'm just following Greg's directions and trying 1-2 pumps/day, still experimenting. I'm taking several things to reduce ammonia: L-carnitine (liquid), ionic molybdenum, ionic manganese (high ammonia depletes it), silica gel, zinc, and OKG (ornithine alpha-ketoglutarate). I was taking Na-K-Butyrate, but stopped when I got my EBV antibody test results (sky high). Should I be taking BH4? Or something to help me produce it? And how do I stop producing so much ammonia? I don't know what to eat anymore. I'm off dairy & wheat, and thiols have been causing me some problems, so I'm being cautious with them. I've eaten a lot of bison for years (it's a Montana native), but now that's driving up my ammonia levels. Thank you kindly. Your suggestions & encouragement are precious.
