I've been using IronFox for a week or two now and added their repo earlier in the week. Haven't noticed any difference from Mull (which is a good thing). It's definitely replaced it for me.
I take both, Mydayis (50mg) and Strattera (10mg). Both is an instantly noticeable improvement over one or the other for me. I stopped drinking espresso/coffee also (not caffeine, just mass doses of it). I'll never be perfect, but I don't fly off the handle near as much as I used to.
All of it. You should generally be unseen.
