Wanna

Currently I am taking both Provera and Metformin. Should I be taking both I have the usual side affects.

Provera ?
My dr says prescribed 15 1 a day as of late I take take maybe 5 or 8 and I get my cycle.

Metformin?
As I said the usual side affects but sometime I get dizzy spells I don't know if I am eating enough or often
