Low dose of Modafinil?

marcbra

Hi everyone.

I've been using Vyvanse for a while but it's hard to get the right dose (sometimes too much, sometimes too little).

Today I decided to try Modafinil for the first time and i took 100mg when I woke up (no Vyvanse today).

Three hours later, I couldn't resist taking a nap.

Although I didn't sleep deeply, I felt that for a brief moment I slept lightly. This would never have happened with the vyvanse.

Further more, my levels of procrastination are super high today.

Should I increase the dose to 200mg next time?

marcbra Hi marcbra, welcome to the forums. 🙂

What are you taking Vyvanse for? ADHD, narcolepsy, etc?

Modafinil has been shown to reduce symptoms of ADHD but it may not work for everyone. Stimulants like amphetamine (Vyvanse) are still the most effective for ADHD.

Modafinil's mechanism of action is rather complex and it affects neurotransmitters like dopamine, orexin, noradrenaline, and histamine to name a few.

In contrast, stimulants typically affect just dopamine and noradrenaline, and to a lesser extent, serotonin.

Maybe increasing the dose to 200 mg would help but it will also increase the side effects.

Regarding 'finding the right dose' with Vyvanse, if I were you I'd ask my doctor to prescribe instant release (IR) dextroamphetamine along with Vyvanse. Vyvanse is basically extended-release dextroamphetamine so they're not contradicted.

This treatment option is not uncommon. The tablets come in 5 mg each so it's much easier to titrate the IR dextroamphetamine dose until the appropriate response is achieved.

Are you prescribed lisdexamphetamine? If you are, the dose should be fixed.
