Drug addiction - rehab metaphor video
I think it creates an effective picture of the importance of not getting reliant on certain substances.
One of my vices in alcohol, I get the high for the night then the next morning feel awful. It sometimes creates a cycle as I feel hungover I drink to offset the withdrawals and then feel even worse the next and so on.
That effect is what the video describes and it's important to keep in your perspective if you struggle. The acknowledgement that this is short term and comes at a cost.
