Hi I'm 52 years old and in good general health. Exercise 3 times per week. Abound 3 months ago very exhausted every day no matter if I slept 6 or 10 hours a night. Now for the last 2 weeks I have been nauseated every day. Doesn't matter if I eat healthy or a cheeseburger or just a snack its constant. I had a awful UTI last week after Thanksgiving but still feeling weak and sick.any advice? Also, had a tubal 10 yrs ago so, not pregnant. Thank you, Penelope
