does anybody else get extreme dry mouth and throat right as they lay down for bed? i swear im drinking water during the day and epically at night. i have a bottle before i go to bed and i take another bottle to leave on my night stand which i finish by morning. my lips are not chapped and i cant find any other signs of dehydration that im aware of and it ONLY happens at night. is this just a hormonal thing? any insight would be greatly appreciated! TIA😊
