These definitely sound like panic attacks. Even without insurance, you can get help at a community mental health service in your community. I strongly recommend it. Drinking and drugs only represses the panic temporarily..you have to get it treated, or it will continue to distort your way of life.
In the case of ADD, just having the right job and environment can help get rid of the anxiety (usually a creative and non-judgemental environment helps).
In the case of hypoglycemia, a diet that avoids sugar, refined carbs, and stimulants like caffein, etc. helps a lot. Read the book, Potatoes, not Prozac, by Dathleen DesMaisons.
So you COULD to get into a Yoga class and work on breathing and relaxation. What I realized about the Paxil for relaxing is: it's going to stop working and I can't increase the dose forever, so I should work on relaxing more naturally.
Please try to cut the drinking down to just Red Wine a couple a night!
