I'm 28, female,5'4"and 170. I'm currently nursing my 10 month old. No current lifestyle changes. For the past month I have been having what I describe as dizzy spells, nausea and tiredness. it started out being on and off and now for a week its all the time, sitting or standing. Laying down helps. I've tried drinking more water, eating at specific times changing foods drinking caffeine and nothing helps. I'm always dizzy and tired...my menstrual cycle has not returned yet either.
