When I started taking Wellbutrin for my depression, I felt as if the entire world had slowed down. I would turn my head, and the world didn't keep up. It was a weird effect, like time-lapse photography. I had to wait until what I was seeing caught up with where my eyes were. I was vibrating all the time, too. Literally buzzing.
After a while, I acclimated. I could see properly, I stopped vibrating, I could sleep. I was in synch with the world.
When I went off Wellbutrin, I had the opposite effect; I couldn't keep up. My thinking was sluggish. I couldn't get motivated, and I couldn't keep up. Freeway driving was horrible; everyone moved so fast that I couldn't track the other cars. After a few months, the effects subsided or I acclimated.
T was a lot like that. My sex drive went through the roof; it went down after a year or so, and I have even more control now. I was super jittery and couldn't sit still; I'm still less relaxed than I was before T, but I've calmed down some since then. As for the rest of the effect, I just live with it. It has become my new normal. I am still learning how to deal with my new reality, but some of that is situational, and T just heightens effects caused by other things.
Still, I wouldn't want to relive that first couple of years. It's a good thing you have the gym.
