Well at one time I weighed 335 lbs. and now I am down to 235. My problem was simply eating too much and eating the wrong things. Before I ever got that large I was in pretty good shape. I only weighed about 210. For my frame that still gives me a 32-33 inch waist because I’m 6’1 and have short legs and a long torso (30 inch inseam is not very long for someone that is 6 ft. +).
There really are no secrets to it. I eat healthier and I exercise regularly. There are still times when I may stop by Wendy’s or some other food-o-crap outlet (although most of them do offer something healthy) but I don’t make a habit of it anymore. And I put in a few more minutes of exercise when I do (most times). Home cooked food always taste better IMO. And I have to have my veggies. I love them. I also found by taking a mens multi vitamin it seems to curb my apetite. Perhaps that’s just perceived though. I’m not really sure. If you do have to eat out often though try to pick things that are healthier.
One of my biggest downfalls has always been breads. I love them. I also used to indulge in quite a bit of ice cream and sweets but I seem to have lost my sweet tooth and hardly ever have a craving for sweets. I still love breads though but I try to stick to multi grained and whole wheat.
Your goal though seems to be way too ambitious and you may be setting yourself up for a big disappointment. I went through many of those before I finally got it right. Just remember if things don’t work out like you want don’t give up! Give yourself a break and just try and stay focused.
Don’t over do excercising and don’t starve yourself. I know from experience those things are bad. Just think a little bit at a time and eventually you will reach your goal.
I want to get down to 190-200 and then I can finally go shopping! Yeehaw! I look pretty stupid wearing these clothes that fall off me, and they make me look pretty fat (okay, 235 is still fat, but I’ve done good and I’ve went from a 48 inch waist to my most recent 36.) I buy 1 or 2 things every time I lose another 2 inches. You also must not focus so much on the amount of weight you lose and instead focus on the inches you lose. Exercise promotes muscle gain. Muscle is heavier then fat and even though you may lose 5 pounds of fat, you could easily gain 5 pounds of muscle. Providing you do exercise. I also agree that lifting weights is one of the best things you can do. But walking, stair climbing, bicycling & any aerobic exercise can be equally as rewarding as lifting because it promotes stamina, muscle gain and fat loss too.
I work nights and have a flight of stairs I run up and down when I work out at work. I also use an ab wheel and love it because of all the upper body it works. I remember 3 years ago it killed me to just walk up that flight one time. Now I can easily go up and down 20-25 times. And that was just by gradually working up to that. Within a month or 2 I bet I can get to 30-35 times. I realize that isn’t like running up 20 flights because half the time I’m going down, but not bad for a fat old man like me. 
Going out once a week to get hammered though is a poor choice. If it’s just a drink or 2 then I don’t see much wrong with that but you do make it sound as if you normally drink more often then that. If not, then cool.
You really, really, really must consult a doctor first. He/She may want to run some tests on you first.
Did anyone mention that you really should see a doctor first???
Good luck and don’t be too hard on yourself if you slip a time or 2.
btw- I had no problem getting my wife pregnant when I was that heavy so I don’t see what that has to do with it. IANAD though.
