I feel like the effect has changed for me recently. Before about 3 months ago, things like caffeine seemed to calm me, so I self medicated with caffeine often. It helped improved my moods, and it never really had the effect it seems to have on most (alertness, hyperactivity etc.)
I started taking Adderall about 4 months ago, and at first it was extremely helpful. It was like someone turning on a light in my head, and I could suddenly think. I didn't realize how terribly my mind had been working until then, because I never experienced anything else. I originally was taking it for ADD, which is what I thought I had. Maybe I really do, but I noticed that I had almost no improvement in any areas of my life, even though I was trying. I still had all the same problems pretty much, minus severe mood swings/depression. If anything it was harder, because I couldn't get myself to apply that thinking power to anything other than my interests. It made it very hard to do anything other than things related to my interests, and made me even more lost in my own world all the time. I couldn't eat, not because of a lack of appetite, but because I simply could not pull away from what I was doing while I was on it.
The fact that I was able to think is actually what led me to realize, looking back on my life, that my problem was probably something other than just ADD, so I started doing research about all my "odd" behaviors as a child and wound up reading about autism.
Weird thing is, now stimulants more often make me feel hyper for a while, and then afterwards I feel much more sensitive to everything, and I am a lot more likely to get extremely overwhelmed by sensory things during this time, to the point that I often can't function at all, which isn't common for me. It no longer seems to have the calming/clearing effect.
Has anyone had similar experiences with caffeine or other stimulants?
