huge accomplishment (weight related)

so i joined the gym in the beginning of january with a girlfriend of mine. i was at 151 lbs (the most i have ever weighed in my life, I am 5'7 ) i said never again will i weigh this much, i said i wanted to be down to 135 (my ideal weight) by the wedding,,,, and i weighed myself on friday night to find out im at 139.5 !!!!!!!!!!!!!!!!!!!!! i am sooo happy it almost brings tears to my eyes, (i know its so stupid) but i havent felt so great about myself in soo long & here i am! So ladies,,, anyone who is thinking about loosing that extra weight before the wedding or in general, its possible and doable.
i go to the gym 3-4 times a week and just do cardio about 40/50 minutes, i walk with 5lb dumbells on the treadmill and then do crunches,
drink lots of water, subsituite dark/whole wheat bread instead of white, i stopped putting sugar in my coffee :( - i cut out potatoes from dinner, and stopped delicious desserts at 10/11pm.
It all adds up.
Just wanted to share
