I got myself the parts to study for the university, I will refrain from harder / dangerous stuff like Ritalin. The effect lasts for a long time, but has its phases.
After taking mostly I feel really rather limp / tired, without being able to sleep. After some time I'm back aufgepusht for 2 to 3 hours. After that, it stops with the increase in output. But you can sleep still does not. Who is so "smart" and a capsule by 18 clock starts, which makes a high probability through because he circulated only in his bed without being able to fall asleep. Even when I took a capsule times against 14 clock, I could not fall asleep ago 5 clock anyway. Around midnight I was tired and went to bed shortly, but already changed the phase again and I was wide awake.
Side effects / -Effects:
For me it stimulates digestion anyway, so I'll take the capsule (1 to 2 times per week) usually after a meal. Hunger and thirst decrease. It also comes after the capsule for the drainage. For 12 hours you have to empty his bladder ever, unless you hold it.
Unfortunately, the product is very expensive if you really just want to test. Because everyone must test how the capsules acts on yourself. For the university me glucose helps probably more. Because when I was in aufgepushten phase (2-3 hours as I said) am, I am much too fidgety and let myself be distracted by other things. Only then I can focus on learning me again.
