Here are the patterns I noticed from your diary entries, going solely by what's on the page. And I may be totally wrong in my observations, but I'll leave that judgement to you. I offer them purely in the spirit of things you might not have noticed yourself....
1. You have a tendency to run for the medicine cabinet (or worse, the liquor cabinet) whenever you have anxiety symptoms. This is probably dangerous to your health, at least in indiscriminate combinations, and may well be making things worse. You may eventually end up benefiting from cognitive therapy to increase your coping threshhold, which might allow you to be less dependent on meds.
2. There's a certain amount of anticipating trouble, or waiting for the other shoe to drop. Anticipating anxiety can cause...well, anxiety!

For example, hypohondria: getting a mosquito bite and wondering if you have West Nile Disease, etc. You also seem to be monitoring your bowels extraordinarily closely, when the truth is that people do get the runs or constipation without it necessarily portending anything.
3. Night sweats are often from excessive drinking. Even after you stop drinking, it may take a while for the body to recalibrate its metabolism, but I would imagine that eventually the sweats will stop.
4. Vertigo, vision problems, fatigue, etc, can all be physical manifestations of anxiety. If the doctors aren't finding any physical causes, then the answer is probably above the neck.

If that's true, then dealing with the anxiety first and foremost should relieve at least some of the physical symptoms. (Mind+body connection.)
Only my opinion, which is worth...well, not much really.
