It's that time of year again (Christmas poem)

On the first day of Christmeth, I took 20mg,
It sorted out my anxiety!
On the second day of Christmeth, I took 30mg,
Planted several shrubs,
And it sorted out my anxiety!
On the third day of Christmeth, I took 40mg,
Played with my friends
Planted several shrubs,
And it sorted out my anxiety!
On the fourth day of Christmeth, I took 50mg,
Gabbled lots of words,
Played with my friends
Planted several shrubs,
And it sorted out my anxiety!
On the fifth day of Christmeth, I took 60mg,
SAW WONDROUS THINGS
Played with my words,
Planted several friends
Gobbled all my shrubs,
But it sorted out my anxiety!
