I told you earlier this week how he discovered a 14 centimeter round cell sarcoma in his stomach last year.
He had it removed and this week began chemotherapy at Greater Baltimore Medical Center to kill any other traces of the disease.
His wife Carla has been by his side at the hospital.
Here, he writes about his first day of chemotherapy:
Arrived at the GBMC at 7:30 a.m. to get a double port put in my chest. This will allow them to run two different drugs that go into my main artery at the same time. They don't put you to sleep for the double port, they numb the area and you can feel alot of pressure, some blood running and some pain.
I waited seven hours to get to a room to start chemo. Completed the first round of chemo and they put five different drugs in me. I thought they were going to put me to sleep but they kept my butt up and I felt everything - it was a little painful. The chemo started last night at 8 p.m. and won't stop until Wednesday night or Thursday morning.
I am one day into treatment and all it is IV's running day and night. I got sick today, nothing serious but I started sweating, felt flush and the nurse came in with some medicine and I felt so much better.
Now it's 7 p.m. and I am waiting on some food from Ruby Tuesday.
A brother has got to eat good.
