i keep feeling a bit sick..waves of nausea. not really bad but ive been like this for weeks now. im definately NOT pregnant.its usually a couple of hours after eating..almost as if im feeling really weak and low. if i have a glass of pure orange juice i feel a bit better. sometimes in the middle of the night i wake up and feel as if my body is shaking on the inside.. a bit like a tremor. once i felt it in my head and neck. a few times its felt like my ovaries are shaking.....weird. quite often i get palpatations when i wake up at night
