Creating a low mem TSR in Watcom C/C++ 11.0

I'm trying to create a TSR i Watcom C/C++ 11.0, but no matter what I do, I the TSR i create uses AT LEAST 15 Kb of conventional memory. The problem is that I have to include everything from the _PSP to the end of the stack (Including the C functions I use, like sound() ), to avoid crashing. The ideal would be to include a single function in the resident part of the program, but then I'll loose the stack (And thereby my variables).
How do I create a TSR which uses 2-6 KB of conventional instead of 16 Kb ? I've created several 2-6 KB TSR's using Pascal (A very long time ago) so I figure the same thing is possible in Watcom C.

If your problem is the stack avoid variables using the satck. Declare all variables as static and no stack will be used for them.
