So I wake up around 3am with a panic attack, heart racing, anxious, not feeling right. I'm no stranger to these, although it happens infrequently and I have not had it in a long time(I don't think I've had another one this year). Normally I just go on the computer and feel better within an hour. This time it felt a lot more intense, I dont think it was just a panic attack. I was freaked out so my plan was to take potassium supplements drink some coconut water and head to the ER. So I took 300mg of potassium gluconate and went to the store to get some coconut water. I would have consumed a total of around 1500mg of potassium. Not long after the panic went away and for some strange reason i had a surge in libido. I usually have none. At this point you might just be thinking "duh, you just had potassium defieciency". But every time I start supplementing with potassium and coconut water eventually I start getting spacey headed and other negative symptoms. Surely 1.6g of potassium by coconut water and 400mg by supplements is not too much? If the RDA is 3.5g. Could the optimal range for me really be that narrow?(e.g 1g positive effects, 2g negative?) Could this be a sign of kidney dysfunction? I've read some people doing the 20 bananas a day diet consuming around 6g of potassium a day with no issues. The only conclusion i can come to based on my reaction is either kidney issue or potassium is antagonizing something. I've had two 24 urine tests in the last couple of months both times with high creatinine levels(30mmol/24 hours (7-22)).
