Hey. I actually think I was just lucky. Meto is a prescribed by doctor drug here, too, but I just went to pharmacy and asked for antiemetic. They gave me meto without any problem. And we are probably in different countries, so I can't really say how to obtain meto for you...
Upd: have almost 13 hours left. I woke up at almost 2 am and wasn't able to get back to sleep... But now I'm alright. Also, I'm used to eating 2-3 times per 3 days, but it's still feels sad. I don't feel need to eat or weakness (last one is a surprise), but growling of stomach doesn't sound good.
Also, I really want to drink tea. Choose hot water instead. And I also finally went to shower, turns out we got hot water here too, so now I'm just happy. Feel a bit nervous.
