I feel this poems smoothness is a little lacking. The idea is there, and it is a wonderful one, however, the last two lines don't give me the same feeling as the rest of the poem. I understand you are trying to contrast being a giving person versus being a lying person. You write about how simple it is to give, and smile, and then you write about how yucky it would be to die with regret. However, having the pain and misery dissolve into dizziness, doesn't show me why I shouldn't lie or why I should give. I think the poem needs more contrast perhaps. Also, I think you need to use a spell checker before you submit. Other than that, I think you have real potential, with a great insight.
