Nash, good luck, I am pulling for you.
Everyone here is right though about you getting into rehab. Getting clean for the moment isn't beating this thing. I know the nature of these drugs, use them everyday in my job (I am an Intensive Care Unit Nurse for the Army) and I know the negative side effects of these drugs. I have also known quite a few health care givers that have gotten hooked on these things.
Support from friends and family is important to the rehab of an addict. Few people can get past this without outside help, the streets are littered with addicts without a support structure. As screwed up as a flight sim message board can be it is better than nothing.
Nash, please get into some kind of rehab, there will be people there who can check up on you regularly. Don't think that this is a controllable addiction, it isn't. The support groups in NA has people who have gone through what you are going through, they know the addiction, they know the cravings, they know what it is like to 'fall off the wagon'. Very few of us here do, I don't, so all we can offer is moral support. While that is better than nothing it ultimately isn't much and people with a background in this will do more to get you clean than anything else.
Pulling for you bud.
