Not that I encourage you to do so, but here's one way: $$\Theta \left(N\log\left\lfloor\frac{1}{N\epsilon}+1\right\rfloor+ \frac{1}{\epsilon+N^{-1}}+\log N\right) $$
For $\epsilon = \omega(N^{-1})$, the $N\log\left\lfloor\frac{1}{N\epsilon}+1\right\rfloor$$\log\left\lfloor\frac{1}{N\epsilon}+1\right\rfloor$ expression is $0$, and the left expression is $$\frac{1}{\epsilon+N^{-1}}+\log N = \Theta(\epsilon^{-1} + \log N)$$
For $\epsilon = \Theta(N^{-1})$, the whole expression translates into $\Theta(N)$.
For $\epsilon = o(N^{-1})$ you get: $$\Theta \left(N\log\left\lfloor\frac{1}{N\epsilon}+1\right\rfloor+ \frac{1}{\epsilon+N^{-1}}+\log N\right) = \Theta\left(N\log\left\lfloor\frac{1}{N\epsilon}+1\right\rfloor+\Theta(N)\right)=\Theta\left(N\log\frac{2}{N\epsilon}\right)$$
