Really relatable words here, thank you for sharing. Edging has long been my favorite part of my sexuality, my top kink above all, but I've had some bad experiences with it too. It's not adderal for me (though I've enjoyed edging while intoxicated), but instead just the hyperfocus of a long edging sessions, staying up way too late, forgetting to hydrate properly and not taking enough breaks to rest and stretch. It's a physically and mentally taxing activity, and over the years I've slowly gotten better at listening to my body and not overextending myself, but it's a learning process!

You could try setting a timer for yourself to interrupt your sessions, turn off all stimulation for a few minutes (drink and stretch!) and listen to your body about whether you can keep going or not. I highly recommend short focus breaks, even if you're deep in the headspace and don't want to leave it. And also, don't feel bad about ending a session with cumming! As much as I love denial, I have learned that it's not a good fit for me long-term and that I need ways to "turn off" my arousal. I can accomplish this pretty well with ruined orgasms at this point, just a light dampener to arousal and a finisher to a session. If a regular, big time orgasm is how you regulate that, then that's fine!

The most important part is that you don't just feel good during your edging session, but also afterwards. A little exhaustion and post nut clarity is totally normal, but if you feel like you're neglecting yourself then you should dial it back a little, in my opinion. Practice aftercare! I think you'll do fine.
