constant nausea still!!

Leah
Is anyone else still battling constant nausea?!! I am 18 weeks now and I feel like all my friends who have had morning sickness were done with it by now in their pregnancies! My first pregnancy was 10 years ago and it definitely was not this tough on me. I gag upwards of 12+ times a day, I can barely eat, especially after about 2 pm, and I am just exhausted from feeling so ill all the time. Please tell me I am not alone! Not that I would hope anyone else is going through this too though!
