My wife has been on Freddds protocol for about 1.5 years. She has crashed 4-5 times mainly from not taking her vitamins. Her crashes and recoveries are really slow to develop. Last week she developed stomach flu symptoms. Normally, extra matafolin and potassium begin bringing her back after 36 hours and continue to improve for a week until 100%. I thought it was low potassium, so she has been taking 1200 mg of potassium from salt substitute and 1200mg from potassium gluconate with no improvement. She is also taking 6400 mg metafolin. She is also 7 months pregnant (I would name the kid freddd if she would let me). She has had a mostly trouble free pregnancy until now. I can't seem to get this turned around. The nausea has mostly subsided, but severe lower back pain and low energy and malaise are still prevalent. Any suggestions? Thanks.
