(Never tried them myself, but very intrigued by them.)
I had to conscientiously try and find new "fun" things in my life to replace food, which used to be my treat/highlight of my life lol.
I notice a little less joy, pizza used to make me soooo happy lol. Now even if I have pizza- which I still totally can, I just accommodate for it, but it's just like... okay, whatever here's some pizza, cool. I can have 1 or 2 slices and feel fine and not go hog on the entire thing and have it be this amazing fantastic binge.
That's the best way I can describe it. I could basically always eat before and now I just...don't feel like it lol.
I will say, they are rough when you first start out on them. During the 1st 6-8 weeks I had several instances of maaaaaybe five seconds of warning between feeling nauseated and vomiting.
It settles down after a couple months and it was never bad enough to be a dealbreaker, but it's a fun time.
It stopped me cold and has gotten me almost back down at the lowest I was at after my diet so far and I keep losing at a slower pace but basically without effort.
In terms of pleasure, I'd say mostly no with some caveats. I have fewer snacks, and drink less coke, and I enjoyed both. I don't find chocolate or baked goods as enticing any more, but it's not stopped me from enjoying them on occasion.
It's more that it's stopped me from wanting them as often. I find it easier to tell myself not to grab a snack when I'm already full in particular. Before I might overeat to the point of discomfort.
So when I now actively choose to enjoy those things, I'm more likely to actually enjoy the whole experience.
I'd say the exception is probably coke, which I do find less enjoyable.
Outside of eating, I drink less, but do have occasional beers. I enjoy them.
And my relationships are not less fulfilling, and I don't find my life and work less interesting. All in all, the only thing I don't like is the occasional "egg" burps I get from it.
