You have to consult a doctor to see your condition, you have a serious problem that will affect your life dear be careful take care your yourself, take more water and vegetables. But the is to see a doctor and have a whole check-up to verify what condition you have. The only thing I know trouble with sleeping is high sugar or stress. Anyway, how old are you? If you don't mind.
I will soon, maybe after what my psychiatrist will advice. Although... maybe the psychiatrist will just tell me to consult first instead of just recommending the sleep study immediately haha (I don't know if they can read the results anyway) so maybe I'll just go schedule one sooner. But yeah I can feel how it stresses my heart cos sometimes I can feel it beat hard (not just fast). I think I can say my sugar consumption is okay since I don't like too sweet anymore but yeah I drink a lot of water (fear of UTI hahah). I'm 28.
OMG, your so young still to have this problem, take it seriously please check with a doctor to make sure.
