I've just done exactly the same thing, except I jumped off at 1mg. 4mg is really way too high a dose to detox from but that's not really relevant at this point.
The reason you are feeling so out of it is the Clonodine. This drug drops your blood pressure significantly and just generally makes you feel like a zombie. You should start to taper the Clonodine dose but DO NOT stop taking it abruptly as this can be extremely dangerous.
Do you have medical support for your detox or are you doing it yourself? If it's the latter, I'd suggest you go and see a Dr. ASAP.
What James says about PAWS is right on but I don't think you're anywhere near that stage yet. It took me over a week just to get over the acute withdrawal stage at 1mg so I think it's highly likely you're still in physical withdrawal. This is why I think it's important you see a Dr. You may need other medication like benzos to 'take the edge off'.
If you have nausea, vomiting and/or diarrhea, get some loperamide (Immodium or generic) and take a big dose (like 30-40mg). This will help enormously. If weed is your thing, it also helps a lot with nausea.
Based on my experience, I'd say you've got 2-4 days left before the physical withdrawals peak and you start feeling better. Good news is that once you hit this point, you'll improve in leaps in bounds.
The bottom line is before too long, you
will start to feel a lot better. Tough it out and you'll get there. It's only a couple of weeks out of your entire life!
Good luck
