7-OH-DPAT is a synthetic compound that acts as a dopamine receptor agonist with reasonable selectivity for the D3 receptor subtype, and low affinity for serotonin receptors, unlike its structural isomer 8-OH-DPAT. 7-OH-DPAT is self-administered in several animal models, and is used to study addiction to cocaine.
Day by day I'm falling more in love with you
And day by day my love seems to grow
There isn't any end to my devotion
It's deeper dear by far than any ocean
I find that day by day you're making all my dreams come true
And (So) come what may I want you to know
I'm (That I am) yours alone, and I'm in love (in love) to stay
As we go through the years day by day
(I said, "Day by day")
