I'm in a similar situation but with multiple sclerosis for over 15 years. I love to exercise, however on some days a medium-intensity cardio session will leave my brain functioning at like 50% which is not great for my job. I gotta work hard to make sure my gas tank has enough for all the tasks planned for that day. My neurologist calls it Energy Management.
