I have not really been diagnosed with anything despite seeing a number of specialists. When I'm sick, my main problem is feeling a little like I'm in the early stages of a marijuana or alcohol "high", although I haven't smoked or drank in years (never was addicted either). Nor am I on any other drugs. Things just feel kind of off. After about 24 hours, it's gone, completely. It happens about 3 or 4 times a week. Is this strange or what? I don't really suffer from any physical pain. However, I am very fatigued while sick. I can't think clearly and I'm anti-social and irritable. MRIs, other tests negative. If anyone has experienced this I'd like to know their story. Thanks.
