Hi thanks for your query. This is almost common even other. sweating is also there do not to worry .take more water, electrolytes fruits juices over all more fluids. Now for better strengths & stamina no such medicine but u can v yoga, more good quality protien preferably plant protien, dairy products are helpful. meditation is very good as these two basically come from mind & heart not from others. Take balanced Diet with high protien & do as I advice.

You need to have proper diet along with strength write me on personal chat.
