I slept for two hours and heart beats normal now. It was the caffeine in the headache pill, it has this effect to me but not always. I think I’m hypo. The reason I slept for so long yesterday was because of the double doses of Olanzapine. The day before that and last night I only took one and only needed a little sleep. 10 minutes and now 2 hours and wide awake. Been physically active too when I’m up, like I cleaned a lot of things in the house and didn’t feel tired.
