10mg won't be that strong. It will be sedating but not massively so, so long as you don't take any other downers with it. It's lacking in the usual qualities of opiates. There's no euphoria for instance, bit of a buzz, bit of warmth, but that's about it. It's not massively enjoyable IME, being pure sedation. Avoid alcohol while you're on it. You probably won't suffer the kind of nausea you'd get at higher doses, but alcohol would tend to make nausea worse and we don't want you puking in your sleep now, do we? Half-life is around 20-24 hours so you'll still feel residual effects the day after, but only slightly with around ~5mg left in your system by then. You'll be perfectly functional. Don't be tempted to go much higher if you decide to repeat use in future. ~30mg for someone with no tolerance would probably knock them for six.
