LeeLee,
score them in half and see. it's perfectly fine. if it makes you feel more at ease.
also, pain management works BEST when you medicate before the pain gets unbearable. so say that if you take Lortab when needed every 8 hours. come the 6th , 7th, and 8th hour...if the pain is say bad, but not terrible....do take a scored dose of it. when we wait and wait until the pain is bad enough, the drug is sometimes not as effective or doesn't relieve the pain as best it could. especially with chronic pain.
but this will all come in time. it's a matter of experimenting and seeing what works best at what time and how much.
so yes, if a pill is scored you can split it to half a dose. with Valium like drugs, avoid grapefruit juice when taking it. it messes up the way the pill disolves in the bloodstream.
good luck! you'll be okay, don't worry.
