I'm sure my hair is thinning (PDR, documented SE-Ritalin).

33yo male-no male pattern baldness family history (dads, 68yo got a full head of grey hair)

After over 2 years of taking the stuff-for better@worse i'm concerned about the rising of my forehead hairline. Do other ADD/HD meds do this?, perhaps a change is in order, hey don't the 'real' ADD/HD meds: the (Meth)-Amphetamine medications, treat most folks symptoms more satisfactorily and completly anyway? with Ritalin coming along in the 1950's to encourage folks to use less (Meth)Amphetamine containing medications?

Thanks Ya'll:)
