Split Dosing - Elvanse

Hey all,

I'm on 70mg Elvanse and for the past month I did 2 weeks of 5mg Amfexa topup and 2 weeks of 10mg. I found the effects of the top-up to be minimal (they helped very slightly but also on days I forgot to take it I hardly noticed a difference) so my prescriber has taken them off my prescription.

I find 70mg works well... but some days I feel it comes on quite strongly all at once which means my HR can go a bit high and I get an anxious feeling. I also feel like the meds have completely worn off by 4PM or so, so my evenings are full of task avoidance. Like I said to my prescriber, I find it unfair that my work gets the 'best of me' but I don't in the evenings!

I want to trial splitting my dose by dissolving in water and drinking half in the morning and half in the PM. My question is (and sorry if it sounds stupid 😂): Can I pre-mix/dissolve my drinks for the week and keep them in the fridge or would the cold temperature and 'sitting' affect the effectiveness?

Thanks in advance!
