I'm 25 now, but for the past 10 years, I've frequently woken up nauseous, upset stomach, exhausted (even after a full night's rest), and with tons of post-nasal drip. I appear sluggish and tired in the morning and it leads my friends and family to conclude that I'm just really lazy, but they don't know the struggles I deal with every morning just to get out of bed and stay alert!
I've also been having sinus troubles all my life in addition to having allergies to a lot of things (especially dust and dust mites). The last time I went to the doctor, he said the same thing he's always said, "you experience a lot of stress, so you need to engage in de-stressing activities and sports." Which I understand, but it doesn't help me once and for all solve this problem that's been plaguing me all my life.
What should I do so that I can wake up like a normal human being? What kind of doctor should I go see who can help me solve this problem?
