Congratulations on completing chemo and yes...you feel like a marathon runner dragging yourself across the finish line. In a few weeks a little of the old you will start emerging. You'll continue to need to rest more after doing things...but you will start to want to do things. 7 weeks on I was back working part time...4 hours a day but came home and had a solid hour sleep. Haha. It does get better but it takes effort to get your fitness and vitality back. But resting when really tired is crucial to that too. It took me 6 months to get back to full time work. 2 years on and I'm still trying to get my post work energy back. I might never but I'll keep trying.
