i know this may sound weird !!!

My OB prescribed me progesterone 200 mg take two at night and I be been on it now for 4 days and the first day I took it was around 2pm and I was feeling fine I did not feel any symptoms but the next day I took it around 6 pm and I suddenly felt it kick in and was extremely dizzy and drowsy also another weird symptom happened to me I was feeling like I was drowsy/happy if I can explain myself that's how I felt and until this day that's how I feel.
