30 down, 100 left to go

Options
I feel great losing 30lbs, but I look at things like my BMI and see the road is very long in front of me. Another 100 seems like a lot but I'll do my best to get there. I eat a very healthy diet, my only downfalls being drinking and eating poorly from drinking. I'm currently working out 5xweekly and cut grains and recently milk out of my diet. I generally only eat chicken breast, eggs, and an assortment of veg, just bought my first pack of tofu to give me some variety (not bad). I've lost this 30 in 2 months (I could've lost more if it wasn't for all the celebratory drinks after the school semester). Thoughts or advice on this?
