Switch to an HSA if you can.
Not the best for everyone.
For a low medical cost single guy it is probably by far the best but every program is different.
In our program the HSA comes with higher individual and family deductibles and max Out of Pocket so the FSA with lower OOP max limits and higher benefits is a much better deal in that case. Company even gives $2000 to cover most of it too but many expenses you can use the HSA for don't apply to the deductible so you can be out of $ and still well short of the deductibles/OOP),
The HSA plan moves the middle ground risk to the individual and raises the threshold for the plan to kick in 100%. Costs you less if you don't have expenses, more if you do.
