Fresh off of cigarettes (44 hours) but having trouble finding an ejuice that doesn’t choke me, please help!

I know they’re highly frowned upon and I understand why, but I’ve been using the disposable vapes to see if this was really something that would help me quit cigarettes. They did so I ordered a caliburn koko and it came in the mail today.

Here’s the problem though, the two juices I’ve tried are so extremely harsh and choke me no matter how gentle I am. It’s awful on my throat. I know if I’m not able to find a juice as smooth as the disposable bars or near it that I’m going to end up failing quitting again. Please help me!
