Hey Trebor
I had a bout of leaking at work https://community.prostatecanceruk.org/editors/tiny_mce/plugins/emoticons/img/smiley-embarassed.gif after a three day planning session where I was on my feet for 6 hours a day. Luckily I had a work shirt with long coat tails :)
Another weekend after a bottle of red and a couple of glasses of Glen, I leaked again the day after, when I went for a pee in a cafe. Luckily I had a jumper to casually carry in front of me :)
I suspect the issue is muscle relaxation caused by fatigue and / or alchohol.
When I told my wife, the response was (typically logical and direct) "wear pads, you dope". She was right. If you are going to get tired or tiddly, plan in advance and pad up!
I am also guilty of slacking off on my kegels at the moment. That won't help. I'm trying to get back on track but I suspect I won't get a clear head until after I see the onco.
Good luck!
Pete
