Self employment loss & health insurance premiums

I have been self employed for 3 years.  In the past have been able to use the self employed health insurance premium deduction and still have a positive income.  I will likely operate at a loss this year because of higher business expenses even before I factor in the health insurance premium. 

 

Question 1: Will I be able to (or should I) take the self employed health insurance premium deduction and have an even larger loss? 

Question 2: If I do have any loss this year, am I able to carry over that loss into the next year to offset positive income?  

 

Thank you.
