I have been trying this for about a month and a half. Didn't seem to notice anything at first but I started at 1 gram, going to 2 after two weeks. Now I'm taking 2 in the morning and 1 in the afternoon and I do seem to be a bit more active. However, around the time I upped to 3 grams, I lowered my AP dosage (Abilify from 15g to 10g, this is supposed to be more activating by my understanding). Aside from that, there have been some external factors that have urged me to do more (approaching deadlines). All in all it is hard to say what is reasonably attributable to the Sarcosine. I will continue taking it till the bag runs out though. I feel like I'm surfing on the placebo effect.
