last night i was having a drink of white wine and after a couple of glasses i was really thirsty but couldnt be bothered to get a glass of water anyway i went to the toilet before bed and my urine was bright yellow and showed up bright yellow on the white tissue it really shocked me as anyone else had this really bright yellow urine when thirsty i had a drink of water and ut gradually turned normal through the night do you think its anything to worry about it was the brightness of the yellow that shocked me x
