Hi guys, I'm Crymson. Me and my wife are casual meth users (for now, let's hope it stays that way) and I've found a ton of useful information here. Thanks to everybody for all the great advice and I'm glad to be a member.
As long as you try to keep it recreational, all should be fine.
I would also suggest making sure you are properly hydrated and fed, as well as making sure you have a magnesium supplement. Finally it is very important to make sure you can still get relatively good sleep.
