sick and exhausted

I try not to complain about being sick and always tired as I am very blessed to finally conceive a healthy baby (two years of trying and a miscarriage) and I will never take that for granted but I have a slipping hiated hernia that causes me to basically be cuddling the toilet all day long after I have a long day or do any type of lifting. I feel so useless because of it. All I want to do is puke and sleep. I'm almost 18 weeks and I'm concerned I'll be like this the last 5 months of my pregnancy too. I just want to feel better, have the energy to get things done, and to feel well enough to love my husband!
