Swear away!! I'm with the single mother who had an incurable terminal BC diagnosis and amongst the arrangements she put in place asked for her headstone to read, "I'm still bloody angry".
gigs It really is a bugger. The friend I went through the treatment with found her lump whilst first breast feeding, and feels exactly like you, that Cancer took away her chance to enjoy and care for her baby. And the scan at a year is horrible, you can pretend it has all gone away but it forces you back to all those fears and feelings.
AtoZ Half a pizza? Good grief!! Glad you are on the way to getting the first treatment out of the way. I found the sickness wore off after two or three days. I used to think of it as a bad hangover, it didn't put me off either, I had a few real stonking mild hangovers during my good weeks after our binge drinking, dancing on the tables throwing wigs and prosthesis across the room support group meetings.
I invested in several handwarmers, you can get them in ski shops, saved asking all the time, and they helped with finding veins for drips and blood tests as well as the cold hands, and as the treatment went on my circulation got worse as well (I have Raynauds at the best of times) I ended up permanently clad in fleece and woolly hats 
Also don't be afraid to tell them every side effect, the dosages are crude and they calibrate then according to the severity of the side effects. They kept reducing my dose, all perfectly normal, it doesn't dilute the effectiveness, just makes sure it is the right dose for you.
And do feel you can talk on here. What's the point of experience if we can't give others the benefit of it, as I keep saying to DD's Godmother when she keeps asking if I want to sack her after one of her scandalous exploits!
Off to bed hoping I can wring 8 hours sleep out of 10 hours of sweaty writhing
. Sadly that doesn't mean what it used to mean, as DH and his impersonation of a mini with a broken exhaust revving, backfiring and stalling is relegated to the spare bedroom / snorarium.
