@Nikki7 I have a document called Start Low and Go Slow in my signature link with tips for starting small and working up if tolerated. My suggestion would be to stop and let everything clear out, then restart at a much lower dose so you can handle the potassium requirements. I'm only doing 20mcg of methylcobalamin, 4 mcg adenosyl and 1mcg folate and even that tiny of an amount required 3000mg of potassium per day. I've been able to reduce to 50mg of potassium after 3-4 years. I haven't been able to increase B12 or folate so far. I use Now brand potassium gluconate dissolved in water and drunk four times a day. Splitting up the doses allows you to absorb more.
