Feel sleepy despite taking 6 Dexamphetamine. Going to take another 3. Probably shouldn't but I have to study.
I feel the same way today; I just took dexamphetamine pills #7 and #8 and I'm hoping that I'll wake up enough to get some work done.
I ended up taking 13 dexamphetamine yesterday. Felt ok but still tired. Gone back to taking my regular amount today, otherwise I will run out before it is time to get another script filled.
When I get up to needing more than 10 a day (50mg, vs my prescribed dose of 40mg), I try to take a break from them for at least a couple of days to let my tolerance drop a bit. It's often difficult to find the time to take a break, since I've developed a physiological dependence for dexamphetamine and I'm not much good for anything other than eating and sleeping when I come off it (at least for the first few days), so I have to wait for a gap when nothing critical needs to be done, but I get more work done in one good day when the meds are working well than in a whole week of mediocre or poor days when the meds aren't helping much, so it's worth it.
I have a pill bottle where I put spare pills from days when I didn't take any or took less than my prescribed dose, which gives me a buffer for when I need extra without risking running out and having an unplanned break until I get a refill.
