I had the opposite
I'm lucky to get two hours but I'm not sure which is better. Lol. Motivate yourself and mostly get your body going, ie, exercise

Same for me. I go to the gym 3-4 days a week but let me sit on the couch for a second and I am out. Just had some lab work yesterday so anxious to see how they turn out. Glad to see it's just not me I was thinking it's all in my head .

i get fatigue often and it can come out of nowhere.

This sounds like what I am going through now. I have reached out to my Dr. Will keep you updated. Hang in there ,😁

This happens to me quite a bit. If I sit for too long I will fall asleep. It doesn't matter where I am. On days off, if I don't force myself out of bed I will sleep all day after sleeping the entire night before. I will get out of bed eat something go to the bathroom get back in bed and fall right back asleep. It's horrible and I don't know what to do about it. So to answer your question, yes I have a problem with fatigue as well.
