You can use tums or baking soda. I don’t potentiate this way anymore, I found that the good parts of Adderall (euphoria) don’t last too much longer than five hours. Potentiation can make the effects last a lot longer, but they are mostly the ones most people don’t like, the hyper vigilance, wakefulness, etc.
The best thing to do is to turn your XR back into the IR, just defeat the time release coating on those little pellets through crushing.
I have a pharmacy mortar and pestle that turns them quickly to fine powder. I’ve also used a small mason jar as a mortar and a spice jar as a pestle, a shot glass and screwdriver handle, your a smart girl you’ll figure it out. Just grind and grind until you have a fine powder. I also do this with my IR pill because I snort mine, but it dissolves in water if you prefer oral ROA. For the last couple years I am make a solution out of the powder and put it in a nasal spray bottle, you get the benefits of snorting, faster onset, without having giveaway kit like a mirror, razor and straw out when you are using and you also have to store them somewhere hidden. The nasal spray bottle is also best if I’m stimfapping, it’s easy to redose without losing the fantasy I am involved in. You can also get away with redosing in public I’ve even dosed in a therapy session.
