Mid thirties and so far the longest relationship I've been in was 4 months... Starting to think it'll be always like this

So I've been diagnosed with AuDHD and the more I research and read other people's testimonies, the more I wonder how tf I was never diagnosed. Every time I (m) meet a woman I like, I either get too excited/love bomb/overshare and they run away, or I just... Forget. I try to play it smooth and not rush talking too much but in the process I just forget about them. Then I remember a week later and now I look like a fuckboy texting only on weekends. Usually when we get to prolong it for more than a month its when they are more interested than I am so they dont mind me being flaky with communications and I dont overshare because I am not that excited... But that doesn't last long either. To be fair, I only started meds last year and I can tell I am much more regulated, but now i have the downside that I shouldnt drink alcohol (and honestly I dont want to) and that at night the meds wear off and I stop being funny and charismatic. Has anyone in a similar position found a way to improve?
