For the last several days I have woken up feeling ok...but then suddenly my stomach will start getting nauseous and I'll start lurching but don't bring anything up but phlegm; nothing seems acidic or burns in my throat... and Then I start feeling sick with a headache and sometimes dizzy... I'm an older lady and certainly not pregnant! It sometimes last for several hours and sometimes longer.... I'll call the Dr next week if nothing changes, but wondering if any of you go through or have gone through this...and have any suggestions. Thanks!
