School has officially started again 2 weeks ago for me and 1 week into it, I started having this unquenchable thirst that never ever goes away. 

I went from drinking around 600ml of water a day to drinking 5L of water everyday. Even though I just drank 1L of water, I still feel thirsty and if I don't drink, I break down and simply cry unless I drink. Needless to say, my visits to the toilet has become so frequent, I need to go once every 40 minutes. 

Did anyone face the same situation as me before? Apart from seeing a psychiatrist (which I will), any suggestions as to what I could do to make this situation better? 

Are there any possible long term consequences that could result from this?
