I've been taking Prometrium (twice daily, high dose, with food) for more than a year and at first, I noticed that I also had less appetite and felt less bloated although this is not always the case. Like sometimes, when it hits me and I get that "high" feeling, I'm actually hungrier. I start to crave chocolate and sugar.
I've noticed I have mood swings, from being super friendly and cheerful to being quite irritable and VERY aggressive. I sleep well at night but sometimes, I'll wake up from a really bad, vivid dream and won't be able to go back to sleep for a couple of hours. I definitely have more energy, no doubt about that and I think it's because it relaxes me, my mind, thus releasing much energy. My mind is not wasting energy. I've also noticed I'm recently more talkative than usual.
Other cis- and transwomen sometimes report similar effects to what you describe so you're certainly not alone in this.

Also, do realize that medroxyprogesterone is still in your body due to its long half-life so together with progesterone could be amplifying some of the effects. Who knows?! It's best to wait several weeks to really see what's going on, up to 2 months, I think.
Enjoy the ride!
