Dress warm, and bring entertainment, also something to snack on. They have short, (2 hours) and long (5-6 hours) sessions the 1st session is the roughest as our bodies are not used to poison in our bodies, expect constipation, really being tired, bone chills and aches, maybe nauseous feeling, not able to eat, as all food taste nasty. Blurred vision, all hair falling out, which they say will grow back, I'm in week 4 since my last session, hair is starting to grow.
Now the hardest part, is trying to decide the next step, all of this is life changing, and it kind of hard trusting the urologist, I saw mine 2 weeks after 4 chemo sessions, he didn't draw blood or do a sonogram, and said bladder has to be removed, and with that being done I only have 50% chance of not getting cancer again... maybe I should just trust God and keep my bladder, still doing research.
