Dave Coulier is opening up about his struggles with alcoholism.

Earlier this week, the “Full House” star shared an old photo on Instagram, showing his face injured, along with a lengthy caption about getting sober.

On Friday, he appeared on “Good Morning America” to talk about his experience, including how the injuries in the photo happened.

“I won a few bucks out on the golf course and it was another excuse to go celebrate. I was laughing and having a grand old time and I tripped and I face planted,” Coulier said. “My wife was out of town so I had to send her that picture and she started crying and at that point I realized wow I need to fix this.”

Asked how difficult it was for him to admit he was an alcoholic, Coulier said, “That was hard. That was something that I thought other people were. For me I was a functioning alcoholic.”

He also explained how he wasn’t able to see his actions as that of an addict at the time.

“No I wasn’t and that was part of the problem I was hey let’s have fun and it was thinly disguised as let’s have a great time but I didn’t realize the physical and psychological effects it was having on me,” he said.

Talking about getting sober, Coulier recalled, “I thought, ‘Am I going to be able to make people laugh again, are we gonna have the same good times?’ The choices at the time were really tough but I look back now and think wow I am glad I am past all of those hurdles.”

“I was a drunk. Yes. An alcoholic. I’ve been alcohol-free since January 1, 2020. When I drank, I was the life of the party. I could make people laugh until they fell down,” Coulier wrote in his Instagram post on Thursday. “In this picture I was the one who fell down.”

He explained, “I was hammered and fell, going up some stairs made of stone.”

Coulier talked about his experiences drinking and his decision to get sober, with plenty of support from family and friends, including his wife Melissa Coulier.

“I loved booze, but it didn’t love me back. I decided to make a decision for my own well-being, my family and for those around me who I love so dearly. The mental and physical withdrawal were big challenges for me, but I was supported by @melissacoulier and friends who had already made the journey,” he wrote.

“The psychological and physical transformation has been amazing,” he added. “The sky is more blue, my heart is no longer closed, and I enjoy making people laugh until they fall down more than ever before. Thank you, Melissa, for being by my side. I love you❤️.”

In the comments, Coulier’s wife shared words of support: “SO proud of you. I love you and your strength so much!! ❤️❤️”
