I cannot recommend anything homeopathic in any shape or form so I'll get that out of the way. We'll just have to agree to disagree and move on.
I am interested in your eating and working habits.
I suspect you are working up a large energy deficit during the working day, coming home hungry, pigging out and going to bed before your body has fully processed the mountain of food you have thrown at it. Processing a mountain of food generates metabolic heat, which the body tries to dump by sweating once the temperature rises.
I suggest you eat regularly during the day and don't go to bed until at least four hours after your last meal.
If you are getting night sweats on an empty stomach, I suggest you see your GP as these might be a sign of a variety of disorders, some of which are serious.
