May 6, 2026 - Chemo Fatigue / Rest as Medicine

Tami has been sleeping a lot since chemo. She is exhausted with a capital “E.” Unless she has a medical appointment or needs to go into the office to run a client's payroll, her routine is pretty much: wake up, eat (which is a relative term right now), and go back to bed. Rinse and repeat multiple times throughout the day.

As a first‑time caregiver, I wasn’t sure whether this level of fatigue was expected or if I should be doing something differently. So, I did a quick Google search for exhaustion after chemo.

Google Result Summary

The AI summary of the result stated:

Fatigue after chemotherapy is a common, often intense exhaustion that does not improve with rest. It typically peaks a day or two after treatment but can persist for months or even years. Manage it by prioritizing rest, using light exercise like walking, staying hydrated, eating well, and conserving energy.

Take home message: Rest is Medicine

After reviewing a bunch of reputable online resources returned by the search, and looking for the points on which they agreed, the verdict was pretty clear: let her sleep as much as she feels she needs. At this stage, rest really is medicine.

Tami isn’t up for much exercise yet. I’m hopeful that as the tumor begins to shrink and relieves some of the pressure that makes walking so uncomfortable, the pain will ease enough for us to reduce the opioids significantly. As I stated previously, one of the side effects of the opioids is the food sensation that everything is really dry. So, I am hopeful that with fewer opoids, food will stop seeming so dry to her. If that happens, her list of tolerable foods will grow again, and she’ll be able to consume enough calories to be able to start exercising a bit more and rebuild some muscle and body mass.

Basic Truth about Chemo Fatigue

The bottom line is that chemo kills a lot of cells—both the bad ones and plenty of good ones. The body, being the remarkable self‑preserving machine that it is, immediately shifts into repair mode to rebuild what’s been lost.

The fatigue is made worse by the fact that anemia is common during treatment, which means fewer red blood cells are available to carry oxygen to organs and muscles. And on top of that, as I mentioned in an earlier post, she’s on a pretty significant opioid regimen.

All of this adds up to one simple truth: her body needs her to do as little as possible while it works on repairing the damage.

Oncologist Appointment (4/6/2026) Tami and I met with the Oncologist today. He confirmed what we knew, and shared a few additional details. The bottom line is Tami has Stage 4 colon cancer, and the spread is too extensive for anything other than chemo. As the doctor said, " You can't radiate the whole body ."  He shared median survival rates with and without treatment, but emphasized that each patient is different. So, I will avoid putting an expiration date on my wife, and instead say we will fight, until there is no fight left.  Backstory In October of 2025, Tami began feeling uncomfortable sitting for a long time. She complained of tailbone, and general (severe) mid-section pain. By December and January, it had become so uncomfortable that we went to urgent care, and they identified hemmorhoids and provided PT exercises for Tami to work on. With no resolution, and increased pain, the doctor advised a colonoscopy.  Back to Back Colonoscopies  On March 11, Tami went...

July 26, 2026 - The Journey's End

This will be a very short post. An epilogue will follow with more details, insights, and gratitude after I have had some tme to process.   This post is simply to notify. Tonight, at 9:33 PM, after a heroic fight, a day with her siblings by her bedside and me crawling into her cramped hospital bed to hold her one final time, Tami shuffled off her mortal coil and went to meet our heavenly father.   As much as I am exhausted and devastated, I am grateful that she was resting peacefully when she passed. Her pain and suffering are over.  Thank you all so much for caring enough to follow this Journey. The love and support has meant more than I can possibly express in words.  More to come...

April 7, 2026 - Two Appointments - Both Positive

Post Hospital Stay Appointment with Primary Care Today was a good day. Met with Primary Care, which is standard procedure following a hospital stay. In this visit we were able to establish a recurring presciption for Tami's pain management, which is truly a God send. Tami has been in so much pain for so long, that being able to finally manage that has been a major boost to Tami's ability to cope with all that is going on right now. So, knowing that the pain management is guaranteed for a while is a huge win! Removal of the Surgical Staples The 23 staples from Tami's Surgery were removed. The incision appears to be healing really well. So, no additional dressing or action required on our part. Tami is now free to take a shower. The Bath wipes work reasonably well, but nothing beats a nice shower!
