No, the Adderal has nothing to do with your enjoyment or the amount of enjoyment slots provide to you.
Mostly everyone likes to throw some money into the machine and see what happens because there is always the statement of "You just never know.
Do you have an addicting personality?
I do and I was in Vegas once, had never gambled before sat down and had the same feelings you describe. A bomb could have went off and I would not have noticed or moved. My husband at the time pulled me away but as we walked thru the casino, man I HAD to put money in each machine I went by.
I tried the roullette table, that was fun and I had the same feeling as the slots and at both places I had no idea how to play any of the games.
I actually realized that the 2 times my husband tried to get me away from both games, I became angry. I didn't like that I felt that way and realized at that point that since I have an addicting personality, and it really showed its ugly face and leaving the roullette table is the exact time I realized that.
So for the next 3 days (and we had aonly arrived a few hours before thisd revelation I had) I tried to avoid all gambling. Hard to do there, but I was able to do it, thank goodness.
So everyone or mostly everyone gets some kind of enjoyment out of playing slots, come on - its fun but when that warm comfy cozy, warm and fuzzy feeling is more that just having a little fun, then you need to be careful. And yes, I think sitting there at the slots for literally 12 hours straight is excessive. but I also understand how the time flies because the fun is fantastic.
Please just think about it, become aware of yourself, and then try your best to handle it appropriately.
Be safe and be well
