I've been prescribed 30 mg of mixed amphetamine salts instant release 2x a day for years and just last month or the month before I went to call in my refill and the pharmacy called me back and said that they are completely out and they have no idea when they are going to be able to be getting any in. Luckily I don't ever take my full prescription. And my nurse practitioner who prescribes me was already aware of this because we talked about this. I'm prescribed that much but for the most part most days I just take half of one of my pills. So 15 mg. But my bottle is getting dangerously close and there still hasn't been any update on me being able to get my refills. Soon I'm not going to have any and that's why I've kind of also at the same time been tapering my medication and taking it less frequently skipping more days because I don't want to have a meltdown on the day that I totally run out. I'm hoping that just out of luck timing works out and soon I'll be able to get a refill because this is ridiculous.
