Hi Christine,
You are not alone with being anxious about SCT. I remember crying myself to sleep for days before my planned SCT because I was unsure about what was going to happen and whether I would cope with the sickness and feeling so poorly. At that stage, I didn't realise this forum existed which provides some good patient's experiences of SCT and details of their daily progress. Try not to worry too much. Just take each day as it comes and listen to your body.
When you go back into hospital, I would suggest you talk to your consultant about the sickness feeling and the constant trips to the loo following your chemo. You need to get your doctor to prescribe some anti-sickness drugs on your treatment chart just in case you need them, otherwise if you feel sick during the night you might have to wait for ages until the doctor on call prescribes the drugs. Unlike Tom, I did use the whole stack of sick bowls and took many home with me!!
I hope the harvest goes well.
