I usually don't have a close relation to light beers since i find that the taste is rather weak, the first brand that comes to mind is definitely Bud Light.
It depends on my mood and the situation, but overall i prefer lighter color over the darker one, since the taste is not as strong and it's easier to drink a few glasses.
I agree with you on this, it's more mental than physical, of course the body becomes addicted to Nicotine but the person has a strong will they can fight to stop.
