Get yourself a hair mineral analysis and on a Nutritional balancing plan. The diet plan that I was given along with Sea Salt and the gentle nutrients saved my life. I was hospitalized several times before finding out about NB.
The C will prop you up for a short while, but it won't last. I was on C for about 3 months, and it got me out of bed, but eventually it started to oxidize too many minerals and I found myself back in the hole again.
Lam's protocol does have its advantages, but I have never agreed with his mega dosing techniques. I never mega dosed on C, even while self navigating through his book (I refused to pay those people $300 for a 15 min conversation).
The great thing about NB is that it addresses the underlying conditions of AF. There are many of us here on curezone that can attest to its effectiveness. I was completely bedridden like you 7 months ago. I can now work part time, exercise lightly, and even go out and enjoy myself again. Onwards was also in bad shape and 11 months later she is 95% healed. Marie64 has Addisons and she is now off almost all medications.
Don't waste you money on Lam's consultants. They will only get you so far, and many here like Wiredgeneration ended up way worse after his mega dosing protocol.
His book is very informative and he does know what he's talking about when it comes to AF, but he fails to address the conditions that are likely causing the AF
