Concentration problems effect of Amitriptyline

Due to a significant, chronic sleep disorder, I have o. g. Drug prescribed and taken for about 2 years, regularly, taken. Overall, the effectiveness is good for me, and I have developed no tolerance for this drug, I always take always consistent dose. However, that certainly depends on discipline and consistency. As far as the side effects are concerned, I have already seen a whole series, in particular the weight gain (15 kg / 2 years), which in any case depends on the medication intake. Long-term changes in diet, etc. are very difficult, because on the one hand, I was more hungry and on the other hand, even with changes in diet and physical activity very difficult to no weight loss. In addition, there is still a reduced performance and concentration capacity during the day, but not serious for me, but already noticeable. Then, of course, the risk of dependency, as with so many antidepressants and benzodiazepines. Also, I’m usually pretty tired after getting up in the morning, but that basically comes with me during the day.
