The Craven Cottage side currently have 28 points on the board and could find themselves dragged into a relegation battle.
Fulham were unlucky not to pick up at least a point from the narrow defeat to Manchester United at the weekend and Jol hopes they can secure survival before the final day of the season for the sake of his health.
"First you need 36, 37 points," said Jol. "After that you know about 40 points, it's always the same. If we'd beaten United and had 31 points now it would be finished.
"But if you've got to wait for that until the last game of the season, you'll probably end up in hospital just before that, which is not what you want!"
Meanwhile, Jol believes their business in last month's transfer window will help them steer clear of trouble after bringing in five new faces.
"Normally I hate the transfer window but this time it was a good one for us because we could do a lot," added Jol
"Last time we were robbed of our best players a day before the window finished when Mousa Dembele and Clint Dempsey left.
"We needed this window but it wasn't easy because we didn't have a lot of money. However I still wanted to strengthen the squad."
