Absolute(ly) agree with you there. Tolerance will increase with practice. I remember when a six would work and then a twelve. But before long and eighteen was right around the corner and then high % alcohol (ice, etc). Then in a heartbeat...hair of the dog was a regular breakfast. I remember the first morning I had a pint of Captain Morgan for breakfast to kick start my morning from the eighteen Ice Houses that I passed out on the night before. I proceded to drink 18-24 more ice beers throughout the rest of the day...this was a work day by the way.
Moral to the story...practice will make perfect. A perfect alcoholic. You have a huge tolerance for your age. This is stage one-two of the progression of alcoholism. But, one day out of nowhere...tolerance will be gone. You wont know it until you find out...the hard way. This is early stage 3 alcoholism. Liver is no longer able to process the alcohol as it used to. With continued consumption it can go real bad real quick from there.
Not preaching at you...just sharing my experience. Be careful.
Through much research I have discovered that I am allergic to alcohol...I break out in handcuffs.
