You can drink, you just can't eat for 8 hours.
Make sure you have 4 glasses of SN, each with 25g of SN and 50ml of water.
It is
possible to do it without antiemetics, but definitely not recommended. You'll certainly have to be prepared to drink all 4 glasses of SN after puking multiple times. Do you really want to risk failing? Use antiemetics.
Then again, I'd rather you don't die, so sure, don't take antiemetics! Maybe you'll fail and your life will subsequently improve, and you'll be
glad you failed.
Maybe I just shouldn't have told you anything and let you fail! I hope you've given recovery a very good shot before you try CTB. I understand what it's like to suffer for a
long time and to want to CTB badly. But I also know what it's like to recover. Many people, most people even, do recover, eventually. I hope you bare that in mind. I'm sure you have at least some doubts about CTB, listen to them carefully. Once you've done that, if you still want to CTB, I'm fully behind you. I don't want anyone suffering for their whole life. I'm not pro-life, I'm not pro-death. I'm pro-choice. Meaning I want to help people make the correct, best decision for themselves.
Sorry you're suffering

we're with you either way
