If I understand it accurately, you're interested in the interaction between craving and binge drinking. In that case, add another column in your data table (e.g., calling it BC) that lists the product of craving and binge drinking (after proper centering), and then specify the model with something like

-model 'Age+DaysDrk+Task*Sex*Time*percHDD+Task*Sex*Time*CravP+Task*Sex*Time*BC'

Would the following two lines be what you're looking for?

-gltLabel 1 'Male_stress_HDD_CravP' -gltCode 1 'Gender : 1*Male Task : 1*stress BC :' \
-gltLabel 2 'Male_drug_HDD_CravP' -gltCode 2 'Gender : 1*Male Task : 1*drug BC :' \
