Hi Kpat good to read your a few weeks down the road with your “last trip” ) long may it continue!
I have gone through what you have with regards to those old receipts and bits of paper linked to gambling. Went through an old email account that is still active. 100s of emails from casinos. Tons of “deposit” confirmations. It represents months and months of lost time and money that can not be replaced.
Try not dwell on the past even though it is good to sort through things it can be a bit of a pandoras box. The PC virus you have sounds nasty! AntiMalware is a free bit of software which is really good at digging out the nasty s. But hope you sort it! Here is to a full month without gambling!!
