This is a familiar situation. Very often, the problem is not only in the workload, but also in the internal balance of the body. For example, I recently came across an interesting article about the proper use of medications to support men's health, in particular tadalafil. It explains that there are safe limits for intake within 24 hours and why they should not be exceeded. Here is the link: https://valhallavitality.com/blog/understanding-the-maximum-dosage-of-tadalafil-within-a-24-hour-period. I think it is useful even for those who just want to better understand how to maintain energy and avoid dangerous decisions.
