Using commas with introductory adverbs is a stylistic consideration. Using a comma in this situation is never incorrect, but many writers have recently started omitting the comma. You could also try moving the adverb around in the sentence, expunging this problem completely: instead of saying "Suddenly, the filled cup fell off the table," you could write "The filled cup suddenly fell off the table," or "The filled cup fell off the table suddenly."
