I think I'd say the same, although it's hard to say if it was 'the greatest experience' (and what that means) or just 'pure bliss' due to the drugs.

I've got a bit of a love/hate relationship with MDMA. I tried it for the first time around age 26, and did it about 4x a year the 3 years after, usually with my girlfriend. In the past year I've not done any drugs and am conflicted about where to go from here.

The initial experiences the first year were really just pure bliss in a way I'd not experienced before, and the feeling of being on cloud 9 lasted pretty strongly for weeks, and months later I could still relive the good feelings by recollecting it, or listening to certain music. As you describe, speaking comfortably with your partner was amazing. The feeling of having empathy for a loved one, and receiving it back, was one of the most wonderful aspects of it, the one I probably enjoyed the most, and longed for while sober. (more-so than the body-feel, the touching, the music, all of which was amazing too).

In the second year of use that developed into a more black/white experience of a heavy-upper and then a complete lack of it the day after. I don't think I had any downers, but the contrast between pure bliss one moment, and a very regular mundane living room setting that same evening, was definitely strange. It put the presence or absence of happiness in the spotlight, whereas before I didn't generally pay that much attention to my state of happiness. Feeling bliss wasn't an obsession, and lacking it wasn't an issue. After MDMA, that calculus changed a little bit.

In that year I also realise how artificial the experiences of drugs were. MDMA still gave me amazing experiences with friends and my SO, some of the conversations we'd not normally have really did have lasting effects in a positive way. At the same time, it felt like we were cheating. Feeling comfortable enough on drugs to discuss certain things is great, but it also highlighted we weren't communicating completely honestly without drugs. And lastly, there were some indications that we weren't the same person on drugs, either, and that the drug personality wasn't necessarily the 'real one' that lies underneath without inhibitions. I've seen friends cheerfully smile as they told me their phone was stolen at a festival due to drugs, whereas they lost precious pictures/data and money (which they couldn't afford), and were devastated about this the next day.

I still enjoyed MDMA without any cynicism, but the rose-tinted glasses had come off.

In the third year of use I think I noticed I was slightly less happy generally, and while on drugs the highs weren't as high. It's hard to isolate this, it could have a million causes. But my feeling was my brain has been altered for the worse due to the drugs and that it was time to stop. It's been a year now and I'm quite happy to have stopped. At the same time, an amazing experience unlike any other is a few dollars and 30 minutes away. I'm happy to have tried drugs, but I kind of feel it's probably best for me to stay away from it from now on and treat it like a middle-class family treats a Michelin star restaurant: every few years, on vacation, you may indulge, but otherwise you don't think about it. I think those who can limit it to once a year or even less, will find MDMA is quite amazing. For those like me who went down the rabbit hole a bit and tried it multiple times a year for years (or worse, those who do it every weekend), probably will suffer at some point.
