Has anyone else had 'difficulty' obtaining tegretol xr 200's or 400's?

Our pharmacy never had enough 200's to fill the monthly script.  The
pharmacist said it was the manufacturer's fault.  He said there was no such
problem with the 400's.

After annual doctor's check-up, and discussion with him about the problems
getting the 200's, he wrote script for 400's.

Got the first month's rx of 400's with no problem.

This month, back to the same old same old - only a few days supply, come
back in 3 or 4 days.

This sh*t gets old.

Anyone else having problems with pharmacies maintaining adequate supplies of
tegretol/tegretol xr of any dosage?   Been told the same 'story' we get?

TIA
