It's really no point if you force and stress yourself. I stressed myself with quitting alcohol and try to control not to eat or drink "cold stuffs" for a year. All was in vain. Then, I got pregnant because I let it go and went for chills every week for that month! I did everything in moderation. If I wanted to eat ice cream, I ate half a cup. I drank 2 glasses of beer each chill outs. Stress is the key factor of all.
I would strongly suggest that you stop drinking alcohol while in the midst of waiting for the result, otherwise it might wasted your effort to go through all the process and hoping to get conceive...
