I understand that potassium needs go way up when beginning a methylation protocol. How much potassium are we talking? Hundreds of milligrams? Thousands? And what are the signs you're getting enough? What happens if you get too much?
Potassium needs don't always go up with starting methylation, but very often do. I think a better question is not what are the signs you're getting enough, but, rather, what are the signs of a deficiency, which can include fatigue, heart issues (palpitations, arrhythmia), muscle spasms, insomnia. If you haven't already, it would be good to check out this thread:

Among other things, it contains a link to a thread by Richvank which explains why people with ME/CFS tend to have low intracellular potassium in general, why blood work may be normal and we still can have hypokalemia, etc.
If you get your potassium from food sources, then it is almost impossible (I think impossible actually) to get too much potassium. The daily RDA is around 4500 mg. (and that's the minimum) I developed hypokalemia rather rapidly after starting methylfolate, my chief symptom was severe fatigue (and later muscle spasms). The symptoms abated after I titrated up to 1000 mg potassium over a couple of days, taken in divided doses.
Now I find I need to take around 800 mg a day, plus I drink low-sodium V8 which is high in potassium.
We're all different. You have to find what works for you. Some people here take 3000 mg a day, some don't need any. Yes, food sources are best, but I found I could not get enough potassium from food sources alone.
