Does my throat look normal? Please help

Lately, I’ve had a little bit of a cough, extra mucus in my throat and its been a little dry. When I lay down at night is when it’s the worst. I’ve been vaping on and off for about 3 years but I quit for like months about 3 times. Does this look worrisome?

If symptoms are worse when lying down then it may be reflux.
Reflux from the nicotine you’re vaping.
Go to bed with your head elevated on say three pillows or a “wedge”.
If you sleep better and feel better then it means

(a) no irritant managed to travel up to aggravate the throat and
(b) see an ENT to confirm and he will suggest you stop vaping or if you insist on damaging your health
by vaping, then he’ll prescribe meds to alleviate the symptoms.

I totally agree with Barney. Your symptoms sound a lot like reflux.
I would add to his tip to sleep with your head elevated and to avoid consuming coffee and chocolate because caffeine irritates the already inflamed stomach mucosa and contributes to the loosening of the esophageal valve.
Also avoid sausages, fried foods, and meats because besides reducing the gastric emptying, they unbalance the pH of the stomach.
