Well im the same as you, evenings are my worst time (im also an animal nut
).
When i lost weight initialy following weight watchers it actually allowed me to eat in the evening, becasue id save all my points (calories) for the evenings, though i have a feeling I wouldve lost weight quicker if Id not had so much food in the evenings as alot of dieting advice doesnt recommended eating in the evening due to the facts its the day you need to the energy for.
But the point is, it can be done, i lost over 2 stone in about 5 months, and thats quite alot considering i wasn't too overweight to start with.
The funny thing is that even though you seem so hungry in the evening you will go to bed and then wake up with no appetite, its just proves its all in your head really, and the best way to stop it is to find something else to do, break your usual habit, I think i saw once on Trisha that she lost weight by hand sewing a patchwork quilt, maybe a new hobby would help?. I also found that just logging on to the forums could help as it gave me something to do and kept me focused, especialy reading people success stories!
