I have used it on and off for past 6 months or so- I like it a lot because I experience zero side effects from it, and it works reasonably well. The cool thing is I can eat if/when I want to, but it stops MOST of my cravings, except sometimes I get a really bad craving that it cannot stop.
I just took my first dose of Asenlix today (no Meridia for awhile) as it is supposed to really suppress the appetite and give energy- I just need to see if I can handle it's CNS side-effects.
