In response to AdnanZ's comment.
I disagree with you on the comment about the truth inducing drug. The drug was LSD, which was typically given in sugar cubes back in the 60's and 70's. This historical reference was spot on. Walden, the man administering the drug, can be seen living away from the Dharma infinitive's village. His hut looks like that of a crazed hermit, it is clear that Walden has used this drug quite a bit. Sayid's lack of motivation to escape after the incident shows that the drug made him have existential thoughts about the meaning of the island and the significance (or lack there of) of his time-lost existence.
