Hey, you're already 90% of the way to a healthy lifestyle and losing consistent weight. Now you just gotta track your weight week over week and adjust your calories appropriately. Also, I'd highly recommend weighing / measuring your food. You can't eyeball stuff while tracking, it defeats the purpose.
Beers on the weekend are totally fine. Just make sure to account for that in your daily allotment of calories and you're set.
