Logan Paul has revealed that he has been suffering withdrawal symptoms after giving up smoking weed.
The YouTuber-turned-boxer announced that "boxing redemption" was among his New Year ambitions as he searches for his first win in the ring.
That has led to him quitting marijuana for good, however, he claims that soon impacted him in the worst way and led to the "worst week" of 2021.
The 26-year-old took to Instagram to share his struggles in a candid post last week.
He wrote: "Super fun New Year's story. I quit smoking weed on December 24, been having some pretty nasty withdrawals (loss of appetite, insomnia, extreme irritability) — by far the hardest week of 2021 for me.
"Then yesterday on NYE, I got food poisoning (which was odd because all I had was a tiny croissant and a latte in the morning).
"I threw up 40+ times and spent the evening sweating in bed… AND all the pharmacies were closed so I couldn’t get any medicine. I was so dehydrated that I begged the only emergency ambulance in the city to hook me up to an IV so I could replenish and go out with my friends."
"They said it wasn’t possible unless they took me to the hospital. Obviously f*** that," he added.
He went on: "In an attempt to initiate the rally of the century, I managed to put on my suit and go to the party for 10 minutes before I realized my fate was sealed.
"As I walked back home up the cold icy hill defeated and disappointed, I threw up another five times in the street. Didn’t miss a stride.
"Coincidentally, this is the third New Year’s in a row where I’ve been deathly ill, so I theorized: perhaps life has made the beginning of the past few years a nightmare for me so I appreciate the remaining 364 days. I consider it an involuntary 'reset.' Having been physically and mentally humbled (again), it’s only up from here."
"I'm feeling much better today, and I know this year is going to be astronomical for me. I hope you all grab 2022 by the f***ing horns and accomplish everything you want," he added.
Logan started his boxing career with a bout against fellow YouTuber KSI in 2018. The pair fought again professionally in a rematch a year later, which was won by KSI.
Logan, who returned to the ring with an exhibition fight against Floyd Mayweather last summer, and KSI have now been teasing a mystery announcement for Tuesday, January 4.
