Are there any insulin users out there that can offer any help or advice on using insulin pens (Lantus) compared to using regular insulin in a vial with a syringe (Lantus)? I'm new to using insulin (although I've been type 2 diabetic for 5 years) and can't decide which route to go. Are there any advantages/disadvantages to either the pens or the vails? Any help would be greatly appreciated! Thank you.
