Cultural advice for cutting alcohol?

Over the past year I've lost 20kgs, lowered my cholesterol and bodyfat significantly, etc, but I've been plateaued for a few months now (I'd like to drop at least another 5 kgs and get under 100).

I kicked up the intensity of my workouts, including interval training, but I actually gained weight (muscle) rather than losing fat.

I've started to notice now that, not only have I lost my alcohol tolerance and can feel effects after just two-three beers, but that weight is starting to creep back (back up to 107 after getting as low as 103) and I can't seem to get a good, intense workout the next day after even just a few drinks.

Here's the problem: My business deals with bars and bar owners who keep late hours. I have to go and meet them at their bars to talk shop. Additionally, I live in Korea, where late night binging on both food and drink are often critically important to both business and personal relationships.

I've decided today to seriously cut back my alcohol consumption to just a few drinks per week. But what do I do when I have to visit three bars in a night? I'm afraid ordering water just makes me look cheap and turns off the owner because I'm not contributing to their business, but most of time that's honestly, genuinely, all I want to drink.

A couple other ideas:

Ordering whiskey and sipping on one glass all night. (doesn't help when I have to visit multiple places though)
Find a non-girly, non-alcoholic, low-caloric drink that I can order without getting weird looks.
Substitute drinking for cigars. Bring cigars with me and give them away to smooth over refusing drinks (This one's gonna get pricey... plus increase my cigar consumption).

It just gets so frustrating when I spend all day chugging green tea, eating oatmeal, protein shakes and salads, and then going out to meet people to talk business at night and having multiple beers thrust into my hands. Has anyone else confronted this situation and found a way to deal with it?

I understand the point, and as our company grows I might be able to focus on other clients but as of now, bars (mostly expat bars) are our only clients. I don't really want to get out of the biz for a number of reasons. Not the least of which is that I think we're really on the brink of something big.

I'm thinking I may just have to start flatly passing on the alcohol. I really prefer just being straight-up with people

In response to the light beer question, well, you can get "S Feel Diet" beer, which is regular beer with fiber added. I'm not even kidding. Can't get it in bars though, just convenience stores and super markets.

Generally I drink imported microbrews and tend to favor darker beers, which from what I've read have fewer calories/carbs anyway. Korean beer is not very enjoyable for me.

I could also try ordering wine instead, which I genuinely enjoy more anyway... although people might think it's snooty they might understand me not wanting to slam back five of them at once a bit more.

We're essentially an importer, distributor, and owner/operator of Incredible Technologies games (Golden Tee being the primary game).

We're a pretty small operation, taking it slow and steady, but we're laying a solid foundation for the future and trying to do it right. We're not quitting our day jobs yet, and we're trying to stay down to earth about it, but we're making some real progress.

Thanks Basically, we maintain ownership of the machines and split the take with the bar owners. Pretty standard from what they do in US/Canada/England/Australia. As far as I know we're the first non-native English speaking country to have it though.

Thanks We're really hoping the love for golf will translate into a love for a golf game
