I took creatine monhydrate, as well as citrate. At about 5g I did okay, but anything more than that I urinate like every 10 minutes. I urinate a lot as it is, but I was recommended to take 10g a day of creatine when I tried it before, 5g pre-workout and 5g post. I did this and with both forms of creatine I became so thirty I almost flushed out my electrolytes. I drank over a gallon of water in about an hour and a half.Now someone has told me I'll be fine as long as I don't take over 5g of it. I did enjoy the energy it gave me. I feel I'm lacking in energy, but than again I have been dealing with insomnia a lot and melatonin doesn't seem to help much. I do remember at 5g I felt great, but at 10 I felt like if I drank a river I'd still be thirsty. I don't know if I have kidney problems and I do drink a lot of water, but even when I don't I piss like all the time. Atleast twice an hour everyday. I do take a multivitamin, so perhaps I'm flushing out excess vitamins? I have had blood tests and they always show up normal. This frequent urination has been going on for a long while now. I don't know if this means anything, but as a kid I used to have trouble urinating and now I feel like I have to go all the time.
