Sungyeol went through a dangerous case of caffeine overdose!

The members of�INFINITE were guests on the April 8th episode of Mnet's 'Beatles Code 2'. On the show, Sungyeol said, "For 8 months, I rested by myself because I had no schedule. I wanted to become an adult because I had a kid image." He confessed that for a while, he drank over 10 cups of coffee per day.

Dongwoo added, "Sungyeol crams everything. He drank coffee saying that he'd get used to it. He even exercised a lot saying that he was going to get buff."

His overconsumption of caffeine didn't come without consequences.�Woohyun revealed, "His effort had a negative side effect. Because of Caffe Americanos, he even had arrhythmia. When we were practicing our choreography, he came with all these wires attached to his chest."

Hopefully, Sungyeol learned his lesson!
