There are several possibilities:

1. Are you decoupling LJ and Coulombic interactions simultaneously?  They should 
be done in separate steps, or else you get very large errors.

2. You probably need a lot more lambda points to properly define the curve.  For 
strongly hydrogen-bonding solutes, you should probably include closely-spaced 
points near lambda = 0 (the fully-coupled state), like 0.005, 0.01, 0.015, etc. 
  The curve from 0 to 0.1 will otherwise be ill-defined and prone to large errors.

You also do not say which version of the code you are using.  The free energy 
code has been tweaked in version 4.0 such that topology handling is different, 
and the procedure is actually quite a bit more streamlined, given the .mdp options.

Might I recommend:
