Have you ever been in that situation yourself? How many times have you promised yourself you'd stop gambling only to find you're still doing it today?
Yes, but I've kept my promise since then. I've faced a big loss, so I concluded I shouldn't continue gambling further and since that day I haven't gambled for real anymore, even though I feel tempted to do so sometimes. When you feel to not be strong enough, remember what your goals in life are and how gambling can prejudice their accomplishment if you decide to return on your word to continue gambling. If your objectives are more important than an ephemeral instant pleasure, you will find enough strength to remain loyal to your promise, telling no to the temptations and finding pleasures on another practices and hobbies.
