I have severe dry eyes also. Here's what my optho told me to do.
Use Restasis twice a day.
Use a humidifier next to your head of your bed.
Genteal Gel(Wal-Mart, walgreens, carries it)
http://www.amazon.com/GenTeal-Lubricant-...rds=genteal+gelFor the pain, the genteal gel(severe) can be used during the day also.
Don't sit under ceiling fans, and don't aim your cars ac at you.
Oasis Tears plus -
http://www.amazon.com/Oasis-TEARS-PLUS-Eyedrops/dp/B006R62UZO/ref=pd_sxp_f_pt I've also had punctal plugs put in my tear ducts. Two times - Both temporary and permanent.
Be careful if it hurts pretty bad. you need to go in. Mine had corneal abrasion and perforation. You'll need special drops for that.
