Desrt Flower,

I get a 90 day supply and only pull about 5 days worth out at a time.

I put the 'main med bottle' in a little thermal sandwich size case which I keep in a drawer.

The 'short' supply, I just keep in the cabinet in a small med bottle and use it for my dosages during the day.

I figure the main supply is less likely to be effected by temp or humidity if I'm not openning it all the time...and so far, I have had no problems with crumbling or effectivity.

Maybe this would work for you too.

Sue
