My grandson went to the first class and immediately appeared notes from his teacher, daily – not attentive, not diligent, distracting others from learning, running, jumping, etc. He does not sleep more in the daytime. By the evening just losing his control, gets tired, the nervous system overloaded almost till the morning. On the advice of a specialist from a children’s polyclinic for four months we gave him Strattera. After taking the medicine, the child became more balanced, more diligent, more relaxed. In the daytime (all 4 months) he sleeps for 2-3 hours. Became cheerful, full of strength. But he began to eat worse, lost some weight.
