I just started meth on Friday. (below treatment dose b/c I am so scared lol I'm taking 3 pills once a week) My rheumatologist gave me presnidone also with it. Is this something that will continue once I'm on a regular dose of the meth? And if I'm on such a low dose of the meth, why am I so tired already? I've also noticed I've become a little crabby and less patient in the last couple days also. Anyone have experience or a story to share?
