the tiredness is not a good sign at any time, especially upon waking. just saying, just because Winston Churchill [an exceptional person] got by on an hour and a half of interrupted sleep during WW2 doesn't mean that is wise to imitate even at twice the length, most folk do best long-term, with between 6 and 8 uninterrupted hours. this said, I wish you luck. for me, getting up after only a 20 minute nap is worse than never having had the nap in the first place.
Churchill was odd, I couldn't do those times. There is a polyphasic cycle called Uberman which is only 2.5 hours sleep a day. Not for me, but people do report success with it. But, from what I've researched it's normal to feel some ill effects in the first week or two until the body adjusts. I hacked it out last night till 4am. Done my 3.5h and only just got up. I overslept and hour because my alarm didn't go off, but my partner woke me up when she got up for the school run. Didn't wake up alert this morning at all.
I'll stick it out for a week or two and see if things improve. If they don't I won't be continuing with it.
