My china bike was way more comfy than my CB, less vibes too. I felt pretty good the morning after a long ride. Sit with your back straight, don't bother tucking. Prep the bike properly, follow the weather reports, get sleep before you go. I bet you make it, I know I would.
Don't be afraid to call it off and wait a couple days. No one will laugh. There is no pressure to try it. But if you do try it, because you want to test yourself and the bike, I'll bet $20 Canadian that you make it.
