About 2 months is my longest. It's amazing how that sexual energy builds over time. After about 2 weeks I start to feel quick, masterful, and powerful. After 3 weeks, that energy turns into restlessness; I start feeling overwhelmingly attracted to women, find myself compelled to flirt, etc. Much longer, and I become manic; my mind starts moving so quickly that I become distracted and restless for exercise and social stimulation - feels kind of like a mild but constant need to pee. I sometimes have trouble sleeping, but it's more just that I feel like I'm never tired. 5 weeks, and I feel like I'm going to pop. Weirdly, after about 6 weeks, this nervousness recedes and I even out to just all-around good feeling.
