For the alcohol, like everything in SFQ and life, it's a matter of good - better - best. It is best to not drink alcohol at all.
It is recommended that you go at least twenty minutes before and after SFQ without any food of liquids. That is a better practice, and alcohol would be included in this. However, doing the SFQ meditations (active or sitting) at anytime for any duration, with or without food is good for you. The recommendations are guidance on how to make a good practice better.
At the level III retreat Master Lin told a story of a friend of his dragging him out and going drinking. Master Lin resisted and resisted, but finally relented. However, as part of his testing, he had previous taken the alcohol from one bottle of wine and added it to another. So on this night, he took the alcohol from his wine and added to this friends. At the end of the evening his friend was deeply intoxicated and Master Lin felt no ill effects.
I have used this method a few times, when socializing with my friends. I have had great success with it and felt not effects of the wine. However, one evening I forgot to do this and soon feeling the alcohol. This just related to me the effectiveness of my previous efforts.
As for emotional healing. I don't think that the process is ever over until you are completely in harmony with the universal energy all the time. However, with SFQ you can see how the universal comes into you and helps you heal, and with SFQ you always end up with more energy and so are not drained.
There are not specific meditations for general emotional healing. Each meditation has it's own particular emphasis, which will help you. As you progress with your healing, will be find more and more of your own guidance coming forward to help you.
Stay with the meditations and trust in the universal energy.
You are perfection.
