It isn't meant to be "comfortable". That was clear I think from the parent comment. If you want to live long-term on the government money, it might be possible in a group living situation, with pooled resources. But it's meant to be a floor against abject poverty, not a recliner.
It's not easy but it's not particularly difficult either. The only hard part is if you're living in a suburb that HN readers tend to live in, you'll have to move house and possibly get a housemate or two if you're single so you can cover the rent. But once you accept that, it's really just a matter of cooking your own meals and buying in bulk where possible.
Get roommates in a cheap city, your rent could be down near $400-$600 / mo., that leaves plenty left over for food and necessities. Buy cheap clothing.
