I have the same issue. At some point, I ended up procrastinating for days in a row, being afraid to work, because when I do I hyper-focus and work A LOT for 1-2-3 days until I get burned out, then can't work for another week. So I ended up being afraid to start working because I know I get so much into it, I can not stop until the burned out. What I do now, is to accept more the lazy days, and also when I work, I try to sometimes take it easier, even if it's hard to stop working when you're in the zone. I used to be very harsh with myself whenever I was lazy, but now I understand that's the price to pay for those days with insane high-productivity.
