Extra Extra Rollercoaster

My weight rollercoasters a lot, so I go from Extra Large shirts to Extra Extra Large shirts and back again.
And my underwear and shorts waist sizes fluctuate with the shirt sizes.
Whenever I change sizes, I try to keep the stuff from the other size in storage, knowing I’ll be that size again eventually.
But at some point, I get frustrated, and I dump all those clothes in a donation bin.
That’s when I get back to my workout routine and lose the weight.
Or give up my workout routine, and gain it back.
And need new clothes again.
