Stopping social drinking was tougher than stopping binge drinking for me. What helped was deciding to go 100% cold turkey for a year. It forced me to learn how to socialise sober. Before that it was too easy to opt out of sobriety "just for this occasion".
It’s been a while since I looked at IPCC report. Is the worst case still apocalyptically bad? We’re nearing 1.5 degrees above average and the results are bad enough already. (Not looking forward to another summer of fires like Australia had a couple of years ago.)
