Is there a trick to finishing lines with a tablet pen?

For example, you know when you're drawing a simple coastline and your pen can only go so far on the tablet before you need to stop and reorient your hand (or have a break due to sore muscles)? I find that as I stop drawing, the pen will kind of "flick" requiring me to erase the erratic part before continuing on that line to form a shape/coastline/whatever. Sometimes I'll hold the pen there for a moment but the pen's sensitivity tends to make a little blot as I hover it there.
