Hi Colleen, thank you for responding. I've been on Ibrutinib 560 mgs once a day for about a week now. I was also started on a high dose of steroids to help with the swelling. My thought process and emotions have been on a ride to Hell and back. I deal with intense need of sleep. I feel like I'm in a fog all the time. This I believe is from the steroids. They are now in the process of weaning me off of them. I'm just trying to take each day as it comes.
