I notice that dairy an important factor is in the (good) relationship that I have with dexamphetamine. Both I and my boyfriend notice dexamphetamine faster ‘works out’ when we eat dairy. In addition, we both notice that protein is very important and that our dexamphetamine works longer when we eat lactose-free cottage cheese or eggs for example. We have also noticed that when we consume food during operation of dexamphetamine with lots of vitamin C, such as oranges and fruit juices, this ensures that the dexamphetamine quickly work out. Why does that happen? Is this common?
