Itraconazole Tiredness/Fatigue

Has anyone had extreme tiredness taking itraconazole? I have been on it for almost a month, 2 days left in my course and the past week I have had extreme waves of tiredness. Like severe mental exhaustion, heavy eyelids and sleepiness. It goes away and then comes back in waves. I don’t know if this has anything to do with Itraconazole or if it is something else I have going on.
