Had a similar experience with adderall. Worst decusion I ever made. Totally changed my personality. Made we eccentric, obsessive, hyper sexualized. Fucked my sleep schedule, gave me a weird kind of speech impediment occasionally, etc, etc, etc.

Also found out after I quit that it also probably contributed to an anuersym in my heart.

Highly recommend anyone to stay the hell away from amphetamines if at all possible.
