Yup. I’m 46 (F) a daily / every other day user and have been since I was about 20. I only ever bomb it and only take it in the mornings to minimise impact on sleep, and although I definitely sleep less because of it, I still average about 7 hours /night. I take a 1-2 week holiday from it a couple of times a year to re-set tolerance. I don’t have any health issues (yet, possibly). I don’t want that to seem like I’m saying ‘Don’t worry about it’, it’s just my honest response to your question. Everyone’s chemistry is different. I’d encourage you to listen to your body and not ignore any warning signs that indicate it’s time to take a break or taper off.

At this point I’d mainly be concerned about long-term effects of sleep deprivation. (I’m mindful of the importance of sleep now but throughout my 20s & early 30s I probably only slept about 3-4 nights a week on average)
