hi all, for the past week iv been experiencing a constant dry mouth, sometimes so bad that my tongue tingles, i keep looking up various different illnesses on the internet and making myself really anxious. i wake up in the night and my tongue is stuck to the roof of my mouth, i keep drinking lots (lol & peeing alot) which helps but then my mouth goes dry again. iv been to the doctor for blood tests (which were all ok) and he says its most likely pregnancy related, i do however have a b12 deficiency which can also make your mouth feel worse. do you think i should be worried? iv started getting emotional about it thinking maybe something is wrong? thanks for any advice
