Welcome back! I can't say your name without thing of two things: jujubees, the candy, which I used to ADORE, and also the line in Tom Petty song, Honey Bee, something about "her juju beads are so nice, she kissed my third cousin twice", love that song. I will now have to go on youtube and listen to it a dozen times.
That weight swing between the 150s and the 220s that you describe... I'm so familiar with that territory, I've lived ALL over it! I can so relate to the struggle to stay at the low end of that spectrum!
Congrats on keeping that 50 pounds off, that is MAJOR!
As for the rest of it, you can do it!
