Annoyed with it always being out of stock

Just started this medication not too long ago and it seriously changed my life. I feel amazing everyday, I have so much motivation, I can focus on tasks and get things done. At the end of the day I feel so accomplished. I haven’t been able to take it now for 4 days because my pharmacy is waiting for it to come in stock and I feel the opposite of everything I just described. I love this medication but also hate how hard it is to get. You can’t even get it in advance so you don’t run out completely since it’s a stimulant and have to wait exactly 30 days for it to be filled😒
