Newbie to Trimix

[Usdabeef]

So i am really new to the trimix club. Prescription is at 18/1/10.....probabably a beginning dose. Just gotta figure out which of the medication is keep me hard for too long. Erection quality is 10 outta 10 within 15 mins of injection and massaging. Can have amazing sex for at least 2 hrs with some breaks in between. However, i just don't go to fully flaccid in a very long time. Its bendable to some extent, but just starts to ache for a long time. Which medicine should i have them titrate down as to allow me to go soft after about 3 hrs? I started at 5 units with nothing, then 10, and meh, then 20 units then 30 units, great hard on, but wouldn't fully go down for a while. This weekend will probably go back to 15 units and see what happens.

I am also new to Trimix and Dr. started me at .40 ml which results in about 9.5 out of 10 erection, but also lasts about 3 + hours prior to return to flaccid state. Happy it works so well but would like to return to flaccid in 1 - 2 hours. How much reduction is recommended while still attaining the initial full erection? 78 years here so I assume that is working against me also. Thanks.
