This fatigue feels like I took 3 Benadryls. Is this how it feels for everyone else too?

I am now just getting a Dx of this. I didn’t even think about it until my therapist and psychiatrist separately came to these issues are your cycle so let’s watch it. This month has confirmed it. It has been getting worse and worse and I am in the early stages of discussing treatment. I am fighting so hard to stay awake. I am already on 10mg of Viibryd so idk what treatment is going to be suggested. I see the gyno next week as well as my psychiatrist. If anyone has any tips for feeling like you’re on a bunch of Benadryls I am all ears lol.
