Symptoms of Food Poisoning

i started feeling so lethargic that i couldn't even see two clients back to back. After a while, i just gave in, as i can't, something is not right. I had to hand in my notice at work. And then close to a year before i gradually got back into work of personal training. It almost sounds like you'v got like a really bad flute, like when you get the fluid. You'e just exhausted. Everything aches. The first day i was in now, went 26 times in 24 hours. Some days i was only eating one meal a day. So there were periods where my appetite was so low and i felt so nauseous
