Paleo diet?

Kristen • Hi friends! I`m Kristen! Just here for advice when I need it, and always willing to give input for others who need it(:
I've been having SOOOO many problems since early September; dizziness, nausea, tingling in my stomach, feeling like food is stuck in my throat or not digesting, shakiness, weird cramping, and fatigue. I've just been all around not feeling myself, and I did have protected sex with my bf (also a sidenote I am NOT pregnant), and I have had a HIGH HIGH amount of stress since then (plus I'm already and high stressed person as is so that didn't help). I went to the doctor and she automatically prescribed pills for anti acids so I thought maybe I have GERD but I was thinking of trying to Paleo diet Bc I hear it cleanses your body! I've been feeling worse these pass couple days (more dizzy and very fatigued) so I'm just curious about what to do? Or should i see other kinds of doctors?
