First time liver flush - Important questions

I want to do a Liver Flush and have a few questions / concerns that I haven't really seen answers for. I do The Master Cleanse a couple times each year for 2-3 weeks each and generally eat well and try to take care of myself. HOWEVER...this summer (ahem...year) has been full of festivities and I have found myself drinking way more than normal. Fortunately the parties are tapering down and my will power is building up so things are getting back to normal. I want to do a Liver Flush for multiple reasons but am concerned about doing it after a couple of months of solid drinking...mostly red wine...but plenty of it!! Should I hold off until it's been a week or more without alcohol?

Also, I work weekdays and am off weekends and am wondering what the timeline should look like for a liver cleanse. If I start on Saturday, will I be done Sunday? What about if I start Friday? Will that assure my whole weekend will be spent indoors? Just curious the best time to start this. Ideally, I'd like to do it this weekend, but I actually have sushi plans with a friend on Saturday and am not sure if a flush should follow that or hold off another week.

Also...what about results? I am hoping to improve my complexion, which has become slightly different in my late 30's...kind of bumpy under the surface for the last couple of years and this has never been the case. I also have a hard time losing weight, though I really would only like to lose about 20 lbs or so. Easy to do when cleansing (MC) but hard to keep off, easy to gain back and hard to lose without cleansing. Will these two things (skin and weight) improve after a liver flush?

I really appreciate any insight. I've always wanted to try a Liver Flush but have always been slightly apprehensive. Thanks in advance!!
