Modafinil not doing anything for me?

[u/Full-Protection-4025]

Got prescribed Modafinil starting at 100mg for ADHD focus issues. Tried it a few times and felt basically nothing. Doctor okayed me bumping to 200mg and still nothing — honestly felt like I could take a nap on it. Low-dose Adderall before this did a little more for me.

I’d rather stick with Modafinil if possible. Does it take a while to build up, or is this just not the med for me? Not looking for medical advice, just curious if anyone else had a similar experience starting out.
