After a week at 10mg, I am considering bumping up to 15 or 20mg. Should the dose (oral) be split up or taken all in one shot? Most things I read online suggest it doesn't really matter and all at once is fine, but figured I'd check here. Also I am a bit curious why most things I read online suggest 5mg (or even less) and states that 10mg is the upper safe limit, but around here I've seen 30mg or even higher suggested. Any insight is appreciated.
