symptoms post AV node abation?

I had the AVJ node ablation at UCSF on December 8th, 2025. So, I'm about 3 weeks past. Almost immediately, I felt better, but by last week, I feel pretty bad, as bad as I ever felt with mere HOCUM. I have serious fatigue. I sleep all night and most of the day off and on. Climbing stairs was easier before the procedure. I have written UCSF with this information and am waiting. Does it take a while to adjust? Is this severe fatigue normal post ablation procedure?
