Does anyone else notice that their cpap machine causes extreme dehydration? When I wake up and pee it is extremely dark and most days I feel very dehydrated. I have my humidity on 6 with the hose temp at 85, so it is pretty high. I drink tons of water throughout the day and even right before bed but still wake up dehydrated. It seems to be worse lately and I think this may be because I have gotten into consistently lifting weights and may not be drinking enough fluids. Could this affect this also?
