For weeks now I have found it hard to sleep at night. I can't sleep until around 4 to 5am. for over a week now ive felt nauseous, lower back pain, headaches, ive been very moody. my stomach has been i guess rumbling...like some kind of movement in my lower abdomin. the slightest thing makes me gag. i feel tired all day long even after ive slept from 4-5am until 12-2pm. i had the strangest food craving this morning to make eggs and sausage and pour salsa and queso sause all over it.
