You didn't mention your diagnosis. I have primary (idiopathic)hypersomnia. It's polysymptomatic and severe.
I take 15mg dextroamphetamine capsules (same as dexadrine) 3 at a time.Three will last for about 5 and 1/2 or 6 hours. After which, I immediately fall asleep! The doctor will only let me have 8 per day which is 120mg per day. (I stockpile)It's not enough. I need at least 9. Two capsules dose would be a waste for me. Anything less than a 45mg dose will not keep me awake. I have learned many ways to cope. And I have a few alternative stimulants to supplement/alternate with my dex. Because I have such a sleepy langorous foggy brain, I always take 500mg of choline and inositol with every dose. It pulls me right into focus (I can even remember names of people I just met.I usually don't retain names of people I'm being introdsuced to),but it doesn't have any wakeup benefits. Because I have way too much extended slow wave sleep, especially toward morning,to get myself awake is like trying to come out of a coma. Sometimes, in spite of my waking dose of 45mg of dex,it would take me 6 hours after waking, just to function. Now, I never sleep more than 2 and 1/2 hours at a time. The minute I get sleepy, instead of fighting it, I take my dex and my choline and inositol and go to sleep. I will wake up a little over 2 hours later (when the stimulant has kicked in),feeling absolutely great, having avoided extended periods of slow wave sleep. No aches and pains. No lethargy. No brain fog. No staggering. Then,I have about 4 very functional hours. After which,I do it all over again. I take about 4 naps in a twenty-four hour hour period. (about 8 hours of sleep out of 24) And, that gives me the ability to function for 18 hours out of 24. Before I figured out how to function,a couple of years ago, it got so bad,I thought I was going to have to quit driving, etc. But, once I knew why my sleep was different, I made up my mind to do everything and anything to demolish my slow wave sleep. Garauna is one of my alternative stimulants - green tea - 200 mg of provigil that I swipe from my husband. You do need a holiday from dex. A day or two is plenty for me. And,then the dex works better. I used to fear that I'd get to tolerant of the dex. Not now. Folks like me do not have the best response to meds. Eventially, everything fails me. But, I think the dex will continue to work. It's been almost 4 years that I've been on this dose. Be your own expert. I'm sorry to have rambled. I know how hard it is to sleepwalk through life. It's not a life.
