well, there's at least two issues here:
1. Stims tend to cause anxiety in those already prone to anxiety.
2. We have no idea how you as an individual and your med respond to any particular stim.
So it would be severly irresponsible for anyone to start telling you to try this or that. You're on your own on this one, same as I was, as I'm on meds, too. If you feel confident in experimenting, well that's on you. I, personally, have set off some near manic episodes with too many stims mixed together, so be very careful if you go that route. good luck either way.
