Good morning, @joeeduffy, I promise you’re not alone here! This forum has been a lifeline to so many of us. It really helps to be able to talk to people who have gone through similar experiences. I always picture this group as sitting around the kitchen table like my mom, grammy and aunties used to do when I was younger. They’d sort through ‘the dirty’ laundry of life and solve the world’s problems. LOL. Anyway, my hope is that you feel like you’ve gained a new family. ☺️

Since we’re sitting at that kitchen table right now, I’m going to offer you some hope and encouragement about your husband’s diagnosis of CLL. I know anytime we hear leukemia or cancer it’s an automatic ‘shock wave’ going through the brain and we typically fear the worst.

CLL is usually very slow to develop and progress. Anecdotal comments from hematologists and also people I know who have CLL, this is something you ‘die with, not from’. If it’s any comfort at all, I had ‘the worst’ of leukemias with a poor prognosis, and yet here I am, sitting at the kitchen table with you 5 years later…perfectly healthy. These treatments can work! So please try not to fear the worst because those ‘what ifs’ just cause unnecessary stress and become a thief of time.

Your husband is making some drastic and positive changes in his lifestyle by giving up smoking! Kudos to him! That’s huge. I’m not sure he needs to give up caffeine though, is this something his doctor suggested? A little caffeine daily with coffee or tea aren’t harmful. If it’s coming from colas & sodas, that’s another story. He’ll want to cut down on excess sugars and the negative side effects of those products.
It’s not easy changing diets in the household but a good, healthy diet plan such as the Mediterranean Diet would be a great place for you two to make the switch. The foods are delicious, simple, with healthy fats. They’re also high in antioxidants which can help reduce inflammation in the body.

There are a number of discussions in the forum for people who have Sleep Apnea, needing BiPap machines. Maybe there will be some pointers in how to get your husband started with wearing his. There are many more conversations you can find by typing in Sleep apnea or BiPap or Cpap machines in the search window at the top of the page.
Here are a couple links to get you started:

Was your husband having symptoms that led to his diagnosis?
