As with everything, there are dangers.
But this one seems to have minimal ones... mostly being sick for a while. Think "morning sickness", but not just for the first few weeks.
And then you won't have much of an appetite and even thinking of eating will make you feel a bit sick.
Disclaimer, I haven't tried this drug but have heard of it in a few places.

You could try to impose some food discipline on yourself without any drugs first and see how it goes.
Eating less is eating less, it doesn't matter how you achieve it.
Limit yourself to eating only at meal times and keep your portions to a reasonable size - avoid bringing more than your plate of food to the table and you'll probably avoid adding more food to the plate. Incorporate salads in your meals - some say we should eat salads some 5 to 10 minutes before the meal itself.
A common trick to keep that lingering "hunger" in between meals away is to drink some water. If you know that you are in no danger of starvation, then it is ok to avoid eating for a while. Usually, that appetite will go away within 30 minutes, but drinking water helps not feel it as much.
You can replace water with any form of tea or coffee, provided they have zero sugar - tea is water with herbs (if you make it yourself, don't trust store bought) and coffee is water pressed through ground coffee beans.
Best of luck!

Use smaller plates...
