I don't know if this will help, but are you eating enough protein in your meals or snacks?
Protein raises your blood sugar and keeps it stable for a longer period of time than anything else you eat.
Your blood sugar dropping is what makes you hungry.
I always make sure when I have a snack that it includes at least 5 gms. of protein....and meals at least 10gms of protein.
Also if the Meridia isn't curbing your appetite the way it's supposed to, maybe you should mention it to the Dr. who prescribed it.
If you bought it over the internet "without a prescription", some of those websites offer a phone number where you can call the physician who is working with the online site to see what he/she suggests. There should be a phone number on the prescription bottle to call.
If there isn't:

does have a physician who works with them.
If you've kept a food journal all the time you've lost weight, that can also help you figure out which foods worked best for you in the past.
I know that boredom is a huge food trigger for me.....if it is for you, go to the library or bookstore and find a new novel or take up a new hobby....just get your mind on something else, and try not to dwell on your weight loss slowing down.
I know that's like not dwelling on having an elephant in an elevator with you <G> ......but the stress of worrying about it will start to affect you physically.
Best of luck to you.
