The least durable piece of kit?

Honestly, I’ve been using drops for most trips. If they weren’t durable, I’d be disappointed (not to say reliable…just durable).

M&M’s: I usually find within the first few hours down the trail my supply of M&M’s is almost entirely used up.

Swap those out for Cap’n Crunch cereal (USA candy). That way it’s the roof of your mouth that is the weak piece of kit. 1 piece of the Cap is stronger than 1 mouth roof.
