Pretext: Have ADHD diagnosis, using these drugs on an on demand basis to study instead of taking them daily. Doctor knows about this and is ok with it. I switch between lysdexamfetamine and extended release formuations of methylphenidate, referred to here as "XR".
As of lately stimulants just really don't last as long for me. I've been on/off them for years and even when I grew a huge tolerance to them and needed 100mg of lysdexamfetamine to study, the long-lasting effects of the drug were still there. Whenever tolerance developed, the effects would be less strong... but the duration of the drug would be the same, if that makes sense. Nowadays, lysdexamfetamine/XR methylphenidate last, tops, 3-4 hours. I'm a fast metabolizer, but normally these drugs last 6-8 hours for me. I am also a very good responder, and 30mg lysdexamfetamine/20mg methylphenidate works great for me. Lately however, after an hour or so I get a huge rush, then after 3-4 hours or even less, I crash, can't concentrate for shit and get really hungry. It's as if extended release is acting as immediate release, if that makes sense? Upon consultation with my doctor she just keeps suggesting to up the dose more and more, which does nothing for the duration of it. At the same time, I'm afraid of redosing these drugs after 3-4 hours because I know the drug is still in my system. My doctor has also suggested switching to IR methylphenidate, but the idea of having to take a pill every 3 hours after I crash isn't appealing to me at all.
