When I was on ritalin, I had terrible moods. Extreme seriousness, I became very irritable, anti-social, and my comedown made me very... just. sad. :( I just felt so heavy! I couldn't laugh about anything. My therapist found it interesting when I saw her, because I am usually so giggly and this time I just felt tense.

I am no longer on ritalin (I switched to adderall and am much better) but I have noticed that if I drank soy milk while taking ritalin, my moods were not so awful, and I didn't feel so tense! Also, I am a regular cow milk drinker (kidney stone problem...) and it did not seem to do the same thing as the soy.

Does any one else have this experience?

Were you drinking soy milk instead of dairy milk or in addition to it? If so perhaps it was just the removal of the dairy.

I did drink both at the same time, yes.
