Please help. I had added B12 and found that I could move up fairly quickly to taking 3 X 5000mcg a day sublingual. So I tried adding methyl folate last night 400mcg and had a weird reaction that crashed my nervous system and weakened my Parasympathetic system (digestion ground to a halt). I got uncomfortable wheezing when I took the methyl folate and palpitations so thought it might be a potassium deficiency (?) But adding potassium didn't help. Ididn't realise but I had already had a high folate diet. Last night I could literally feel myself vibrating in bed, so I took a bit more potassium then some high dose magnesium and glycine for sleep, but I woke up like I had six months ago with extreme sensitivity to everything. I hadn't crashed in months, although I've been sick. I have SIBO, achlorhydria and feel like I still need to take betaine HCL, but that is really driving overstimulation in a weird kind of way. Don't know what to do, how to fix this. I had just started being able to go to the toilet again after months of constipation. Can't afford 23@andme yet until end of month, don't know what to do about digestion. How long does this take to settle? Will it still settle if I'm taking betaine? I'm screwed diet wise as all I can eat is avocadoes, green beans, turkey mince. Food is still coming out undigested. Please help, don't know where to start as my head is a mess. @Freddd? Any advice, please? Anyone please?
