(Note: Alcohol and cigarettes appear in the thread, but they're definitely harmful, so I left them out here. If you struggle with alcohol or another addiction, please check these resources from American Addiction Centers.)

7."Caffeine."

8."Houseplants."

"I have so so so many houseplants that when friends who haven't been over before come over, I get a lot of 😳😯😲 faces, followed by intense questioning.

Short version summation: It takes a whole day to check and water everyone. I use 16 gallons of water a week. No, not everyone is watered every week. Yes, I've killed a lot while learning how to houseplant. IDK for sure but close to 400 most likely."

"That doesn't mean I have a whole lot of money to spend — I just can't seem to stop looking at store apps or yard sales or going out to eat when I don't need to. My wife reins me in for a lot of it, but I impulse-buy shit I absolutely don't need all the time. Maybe it's more of an impulse control problem, but it typically always involves money. For example, I bought custom eye contacts based off the Rinnegan and another Mangekyou Sharingan from the show Naruto... I'm 33."

28."Dog collars and dog gear."

"I have one dog. And like 120-plus fancy collars for her. I had to unfollow collar makers because I can't stop myself from overbuying sometimes, LMAO, but it makes me happy, and I never have gone broke over it. I just know I look insane with that many collars, leashes, bandanas, etc."
