When I'm manic, I tend to buy little things here and there, all of which add up. I usually don't make large purchases at once. So what you're doing with food kinda sounds like me.

And yes, I agree that drinking and driving is risky behavior.

But what else is going on? Are you more productive at work? Hypersexualty despite having no sex life? What about energy. It's kind of tough to tell since you're sleeping, but of course, sleep is only one of the 7 criteria for mania and you only need to meet 3 of the 7 criteria

I normally spend a lot of time on the internet, manic or not. So the Internet thing kind of depends on you individually.

I'll spend more time on the internet when manic, but that's usually because I can't sleep due to excessive energy. So, I basically use the internet to kill time. I do develop obsessions on the internet when manic, though. Like, I'll watch a YouTube video of someone snowmobiling (for example), and then I become obsessed with it to the point I start investing in snowmobiling gear and start looking at buying a snowmobile.

If anything, I'd agree you're hypo. No hallucinations, right?
