How do you feel?
Does it do anything for you?
Alcohol is a depressant and desoxyn is a short-acting stimulant and even at 25mgs, it still isn't much imo; so, yea, I don't think it would hurt you to redose unless you have a heart condition or so other major medical issue.
But really, you are gonna do whatever you want to do and no one knows how you feel and how you want to feel...
I never had any success with desoxyn. I remember getting so psyched bc it is supposedly pharmaceutical speed; however, even with no amphetamine tolerance, I felt nothing from it. I would IV and sniff and eat a whole bunch and be very disappointed and felt like a 20mg Adderall or 10 mg dextrostat would have been more satisfying.
