My Fatigue is not going away

I’m undetectable, have been on Biktarvy for 6 months now. I was assuming my fatigue over the past 6-8 years was undiagnosed HIV + Bipolar Type 1 and I was really hoping for an improvement but nothing has changed. I still seem like I sleep every 6 or so hours of being awake and it hits me out of nowhere like a ton of bricks. I always feel recharged after a nap and can push another 6 hours sometimes up to 8 even but like once it hits me nothing stops it. I’ve had to pull my car over before and nap or have my wife drive at times cuz I literally couldn’t stay awake.

Does anyone else with HIV whose on medication deal with this or am I just an anomaly? I just want my life back lmao like I wanna be awake for a minute ya know?

TLDR: I can’t stay awake! Is this connected to my HiV or should I seek other diagnosis

Edit: almost 6 months on medication. I think 4-5 actually.
