Ease in/out flight upward + slow fall

Hi! I’m new to Unity, so I don’t really know what I’m doing. I’m essentially trying to make my character move similar to the Bee powerup in Mario Galaxy. I’ve sort of got the jump/float upward part down, but I’m having trouble adding the slow fall. When I try to add drag after the timer has run out, it seems to just effect the whole jump. I’m still figuring out what to use where, so there’s a lot of stuff commented out, sorry.
