Do progesterone pills make anyone else feel weird??

Idk how else to describe this feeling other than feeling like I just smoked some 🍃 if you know what I mean. Obviously I am not smoking that’s just how I feel. My doctor has me on a very high dosage of progesterone to prevent me from having another miscarriage. I’m taking 200mg 3x a day every day so 600mg total. By the end of the day when I take my last dose about 2 hours later I just feel weird or “off”. I feel light headed, dizzy, tired, my eyes feel heavy, I feel nauseous, I get motion sick, is this normal did anyone else feel like this?? Im glad it’s helping me keep my baby in but I don’t like the way this medicine makes me feel. Are these things all side affects from the medicine or just pregnancy in general?
