Fmu ....

Ok question ladies . You know how they tell you to limit your liquid intake before bed so your fmu is better ?? Well what time do you all stop your liquid intake ? Me personally, I keep a bottle of water to sip on through out the night bc well I live in the south and I feel it's really dry down here and I wake up coughing a lot ! But I don't want to compromise my first morning urine by diluting it by drinking through out the night .
