Reactions to meds... so if few coctails make me less socially anxious and less embarrased to dance.... do I have ethanol imbalance?

how suprising is it, that mind alterning substances make you feel different? Nothing wrong with that... but it doesn't really prove that much. Especially considering the fact that very little group of people can just pop a pill and feel better without doing anything else... most of them need to solve their life issues as well. And I am not talking of eating right merely... it involves interpersonal relations, spiritual questions for many... finding one's own way...
