My personal rules for gambling (pretty much the same for online as for B&M).
It's all about control. That's why >>>> No alcohol -- especially during table games and VP.
Set a daily/weekly/monthly budget as to how much you're willing to put at risk. (Household expenses come first, then allow a smidgen of any left over for gambling.)
Set a cash out goal for each gambling session, and stick with it. (5 x starting buy in for VP and BJ, 10x for slots for me) If my goal is $250, I WD that and leave the game. Any bits over, I can play next day or week or whenever.
Never, ever go over daily gambling budget (no ATM or check cashing at the B&M, or redepositing online)
If I bust out, I'm done for the day. Next day, there's that day's budget/deposit to play with.
If I lose only what I've budgeted, no biggie. But if I redeposit and go over budget and lose that too... I mercilessly beat myself up over it, and since I'm not a masochist, I don't do that -- once or twice was all it took for me to learn not to do that anymore. LOL
Mousey's 2 cents. 
P.S. -- Someone is going to say all that makes gambling boring... Not to me. Money management and betting strategy are all part of the game.
(Disclaimer: I haven't played online for 2 years and won't until depositing and withdrawing are more safe and sensible for USA players.)
Alice: But I don't want to go among mad people.
The Cat: Oh, you can't help that. We're all mad here. I'm mad. You're mad.
