Need to lose 20 lbs

Hi Everyone I'm a guy new to this but trying to lose 20 lbs and be able to fit into my favorite t-shirt again.
The last year I was pretty unhappy so I drank a lot but now I've decided to ditch the booze and comfort eating and focus on eating healthy and exercising more.
Feel free to add me - I'm not sure how :)
