Same thing happened to me when i started winning just like OP.

I won 8btc but then started making stupid bets with 1 btc wagered and lost it all in a matter of 3 hours.
If you have been gambling for more than 4 hours and it is 4am in the morning there then I would say it is best to stop now before it is too late just as it was for me.
Take a rest and sleep it off so you are in the right state of mind before making your next step on what to do with your winnings.
Because as all seasoned gamblers know: A hot streak never lasts and you have to be smart to know when to step away before you lose it all.
