I don't know what my issue is, but for the past two days, I've constantly felt thirsty...despite drinking nearly 70oz of water a day. The weather here hasn't been too hot (although today it's supposed to be in 90F). The color of my pee tells me I'm hydrated, my veins look nice and full, but I've just been SO thristy. I haven't eat anything too high in sodium, either. I don't want to drink too much water because then my electrolytes will be "watered-down". Perhaps it's because I just started working out? Does this happen to anyone else?
