Hello, Tdol !
Many thanks for your previous advice.
1. I feel [like] I'm working my butt off for nothing ; here it's functioning as a conjunction.
If so, can I be understood that the [like] has originally been [a prepostion], but here it's
functioning as [a conjunction]?
2. Re para.2 ; Caffeine stimulates the central nervous system, [causing an increased heart
rate and alertness] ;
Can I consider above [ ] as so-called "Dangling Participle" ?
