Hello PitTony and welcome
As far as I am aware the fact that you have gambled in the last few months will not stop you from starting a DRO. However the person who assesses your situation might want confirmation that you have stopped gambling now. As such I would suggest you wait for 2 month so that you can show 2 bank statements with no gambling. Also are you getting help from somewhere like gambler anonymous? If you can show you are doing that it will also help.
