Thank you for the information,
Night sweating can be due to different causes.
With the hot & fatigue feeling it can be due to an infection.
Change of taste can also be seen with infection.
Upper respiratory infection is a frequent cause of it.
Again alcohol can play a role in causing night sweats.
Sometimes it can be due to no identifiable cause when it is called idiopathic.
In some cases it can be due to anxiety , tension & stress.
There are many other causes for both the problems.
I feel you should get an examination by doctor.
He can then decide about tests after physical examination to rule out other causes.
I hope this information helps.
I will be happy to assist, if you need any clarification.
Please feel free for any follow up query.
