I have been taking Nuvil for about 8 months now. It helps enough that im not sleeping/blanking out during conversations anymore. Probably the most benifit i got from it was a clearer head and with that came a stronger short term memory. For me it does not have the effects of a full stimulant like Aderol, nor the highs and lows. The bad part is that it is addictive and without it I am a witch with a capital B. I find that a strict sleep/wake/med schedule works the best for me. Unfortunatly that mesns my family has to endure it also. Hope that helped.
