Just thought I would post my progress here. I was on a modified Fredd protocol before I started (creatine instead of sAMe and never added in TMG plus Niacinamide riboflavin, magnesium, selenium, calcium, potassium, vitamin c and d plus a multivitamin and mineral. I got myself up to 10mg sublingual mB12 and 1200mcg Methylfolate split into 3 doses during the day. This gave me what I call survival mode and allowed me to manage things still working full time and avoiding mostly everything else. I still have sock and glove constant numbness which I've had for 15 years way before my CFS onset in 2012/13.
I replaced the sublingual methyl with the hydroxy methyl oil at 1 squirt per day in the morning in October. This was a bit risky since I had no idea as to whether I could absorb the hydroxy at all. 1 squirt was approximately the same dose of methyl as I was taking sublingually (assuming
@garyfritz calculations using 5% absorption vs 80% in the oil). I kept my methyl folate just the same as before.
First 2 weeks
Had a lot of weathering through symptoms (dizzy spells, nausea, irritability sleeplessness etc). But at the same time felt the benefit of having the slow stable trickle of B12 in my system as oppose to the morning sublingual dose. This was mainly noticeable in more stable cognitive and physical stamina across the day (less reliance on my folate top ups if that makes sense). I agree this seems to last around 6-8 hrs since I would notice a slump around 3-4pm in the afternoon.
Week 3-5
Histamine type skin reaction started to appear on my forearms where I applied the oil so I started applying elsewhere to try and avoid repeat application too often. All folate deficiency reactions (nausea etc) disappeared but sleep tended to be less on average. The slump in the afternoon still remained. I started introducing a 10 mg country life aB12 sublingual once per week on top of the oil and this seemed to have a beneficial affect. I started noticing that I was naturally doing more and my stamina threshold seemed to be higher (say 25%).
Week 6-8
Histamine reaction update from Greg to say that this rare (great! Love being so unique). He checked all my supplements and suggested I drop down the Niacinamide and active b6 and look at increasing iron. I've upped the oil dose to 2 squirts one morning the other before I go to bed. So far this is only a couple of weeks but it feels a lot better. My sleep seems to be improving now and I definitely feel like my stamina is less fragile. I have replaced some of my individual b vits with b right complex starting today which has some biotin as well so hopefully this saves me some money and also may help the rash problem. Greg also suggested I may have a block utilising b2 since I was taking in excess of 200mg per day which should be miles more than I need. I will give in and get the 23&me test done this Xmas to see if this shows up anything. I am skeptical on this but trying to keep an open mind since I know a lot of people on PR keep mentioning it (and they have a Christmas sale on...bizarre since you may discover something you might not want to know).
Overall the oil is a lot better for me than sublingual so and I will continue trying this. My nerve damage is likely to be a long time healing. Greg advised this may take years to reverse peripheral neuropathy and that damage to brain could be more like 20 years to fix especially as I'm over 40. It makes sense for me to try and achieve a therapeutic dose that aids healing as opposed to using all the b12 up on living. I suspect a long journey is ahead but this feels right. I plan to make an appointment with my gp and get some regular blood tests (including homocysteine) every 3 months to try and monitor any improvement. I will post more when I have it (good or bad).
