What Causes Dryness And Tightness In Throat?

Hello, I am a 24 year old woman. I woke up in the middle of the night with my throat feeling tight and severely dry. Drank lots of water but didn t help. Felt light headed and bloated. Fell back to sleep to awake with my stomach feeling tight, bloated,and full. Lots Of gas! I smoke, drink quite frequently, and poor eating routines. The day I woke with thesr symptoms I went all day almost without eating and ate one big meal and the night before drank and smoked alot. Please help.
