Here are a few I got from a medical web page:
◾Taking risks (1) - in some cases the addicted individual make take risks to make sure he/she can obtain his/her substance, such as stealing or trading sex for money/drugs.
◾Secrecy and solitude - in many cases the addict may take their substance alone, and even in secret.
◾Denial - a significant number of people who are addicted to a substance are in denial. They are not aware (or refuse to acknowledge) that they have a problem.
◾Dropping hobbies and activities - as the addiction progresses the individual may stop doing things he/she used to enjoy a lot.
But seriously, if
gambling/poker is causing you problems in your life, but you can't quit, you have a problem you might need to get help with.
