I am.  It actually started as trying to eat healthier and not losing weight
(although I did want that too) so I think it's a change that I will forever
be able to keep.  Because really all it consists of is eating healthy foods
and cutting out junk.  I allow myself junk if I want it, but I find that I
never do want it.  Like I said in another post, it's all about changing how
you view food.

well see now therein lies a problem.  I usually eat enough to feel like I've
had enough.  Adding food during the meal just isn't possible because then I
feel like I've overstuffed myself.

No, I'm not at all worried about changing what I'm eating.  I know I'm
eating great for me.  I did stumble into something that most people would
call healthy eating and it's working for me.  Like I described to my sister.
I was constantly banging my head against the wall and suddenly I stopped and
went "why am I hitting my head against a wall... it hurts" and I never went
back to banging my head against the wall because I'm aware that it hurts and
doesn't feel good.

and finally... THANKS!!! :)

Yup. That's why they're prescribed to people with eating disorders, even if
there is no visible anxiety or depression. The idea is that the eating
disorder itself either masks anxiety or is part of a loop (I feel
anxious/depressed-I need something to make me feel better-I eat-I feel
guilty about eating-I'm depressed-I need something to make me feel
better-and so on...). The medication helps break that loop.
About half the people react well to them. It seems you're among that lucky
half :)

If you have a lot to lose, things can go pretty quickly at first. First week
doesn't count (water loss), but even after that, things can move fast,
especially if you're a man. I just did an attitude change (eating when
hungry, stopping when not hungry anymore), and weight loss was pretty fast
for the first weeks. Starting from the first week, I lost a weekly
5.5/2.5/1/8/2.5/3/4. So, some week, I lost pretty fast even though I don't
think I was in severe caloric deficit (I don't count calories, but I was
still eating calorie heavy stuff such as chocolate or French fries) and had
more than enough proteins. However, during the last few weeks, I have been
"stabilizing" at a 1.5-2lbs/week loss, which is just fine according to my
nutritionnist.
My theory is that if you're tuning to you body (listening to your hunger),
it will allow for pretty fast weight loss for a few weeks because it feels
that all that extra body fat makes it safe (% current body fat vs % target
body fat is huge). After a while, the body doesn't feel it safe anymore, and
keeps things quiet for a while. That's what happened to me, I have been on
"slow" weight loss for close to a month, and it started right when I started
feeling really tired. At that point, hunger did increase, especially at
times of the day when I had very little hunger before (for instance,
breakfast). I wonder if weight loss will increase again now that I feel less
tired.
The way you describe how the medication changed your behaviour, it's
possible that you are indeed tuned exactly to your hunger. If so, you are
maybe experiencing what I did with bursts of lost weight. I spent some time
writing down what I was eating, and it seemed my calorie intake (calculated
the following day, so I wasn't adjusting) while listening to hunger was
around 900-1600 per day, which is a lot more irregular than what you would
get on a calorie count approach. But even on the 900 cal days (which usually
came after a high calorie day), I really didn't feel hungry for more.
