I have read your post with interest. You seem to have recognised that your addiction to alcohol and cocaine are now at a critical stage, have you not? I have picked up on this and the fact that whilst you recognise that you have a good job, you also recognise that your unhealthy habits could seriously affect that career, correct?
If you are commited to being rid of these addictions and are highly motivated to change, then hypnotherapy can be a very useful tool in aiding you to do so. With severe chemical addiction such as those presented, it would be useful for this to be part of a co-ordinated therapeutic approach to include solution focussed therapy as well as nutritional therapy.
You might be interested in the following information:
"With the proper nutrition and supplements, the brain manufactures chemicals -- like norepinephrine, a neurotransmitter that seems to increase energy and boost mood; serotonin, another important neurotransmitter; and endorphins, the brain's natural opiates -- that are needed to regulate mood and behavior.
Optimal nutrition may also correct the possible deficiences that contribute to alcoholism or substance abuse. "The question," says Alan Gaby, M.D., editor of the Nutrition and Healing newsletter, "is what are the proper supplements? I treated an alcoholic who couldn't control his drinking, but with glutamine, an amino acid, he was able to go back to social drinking and handle it." For cocaine addiction, Dr. Gaby says the amino acid tyrosine is often recommended. Tyrosine is a building block for norepinephrine." From Psychology Today.

Lastly with regard to your previous experience with hypnosis you were probably falling asleep and the jolt you refer to was you becoming aware of the PGO spike firing and occurs just before your brain begins to create dream like images. The PGO spike is a perfectly natural response. Basically just before you start to dream at night your brain produces an electrical pulse called the ponto- geniculo -occipital spike. This also fires when you are shocked or surprised to draw your attention to a new stimulus. Maybe you noticed when drifting off to sleep that you sometimes make a sudden jerking movement. This is the conscious awareness of the PGO spike firing. It can also occur when you are beginning to drift off to sleep as in the example you gave. For more info on this search on PGO spike.

Ps There is no such think as a general recognised hypnotised feeling. The experience is different for each person. There are some observable signs of entering the hypnotic state, but again these differ in each person. Hypnotherapy can even be carried out with eyes open, although closing the eyes tends to produce enhanced effects. The most important part of the equation is the therapy that is applied in treatment.
I wish you well. By the way Ant is correct there are many qualified competent hypnotherapists apart from Mr McKenna that could assist you.
