Awful Cough at 35 Weeks

Stephanie
I feel like I'm almost peeing myself every time I cough and it's triggering crazy Braxton hicks. Overall, it's just making me even more tired than I already was. 
Does anyone know what hot teas are safe to drink right now?  
I hate the honey/lemon water, so I'm looking for alternatives that would still be soothing and help relieve this relentless tickle in my throat.
