Yes it is easy to gain that much weigh that quickly.. I gained 80 pounds in about 3 months.
The important thing to remember is exactly what everyone said...
1. It takes time, don't lose hope.
plus of course..
2. Phentermine just stops your appetite, just taking it doesn't lose weight (sigh unfortunately)
3. I believe they say it takes 20 minutes of workout (regardless of the workout) before the body begins using fat reserves for energy (aka burning fat). Does this mean your 20 minute workout is a waste? Definitely not! You dont lay comotose after your workout do you?? You're body is still burning on the way back to work, etc. In fact, your body continues to burn at an excellerated work after a workout (even if you do play dead haha!)
Keep positive!
