Actually I was going to post a thread with a similar message to this one...
A positive effect:
A while back I wasn't well, then CurlyCpl was ill & we weren't feeling up to it for a couple of weeks (which is unusual for us). At the same time I was really struggling to understand something at work & had spent weeks on the same problem. We broke our dry spell with a fabulous session & suddenly everything I'd been struggling with at work made sense & I achieved more in one day than I had in 2 weeks.
I mentioned to him that I thought the dry spell & my brain struggles might have been linked & since then I've noticed that the morning after the night before I'm always brighter, quicker to pick things up and more productive.
F*cking my brains out? You're doing it wrong!
(no complaints at all)
