non-nausea causing laxatives?

omg ive been constipated my whole life. right now im really, really backed up. like its been weeks.

its because im popping zofran all the time due to kidney stone related nausea as well as health anxiety. zofran is INTENSELY constipating, its basically imodium but stronger and not actually for diarrhea…

i need to cut back on zofran obviously but laxatives always make me nauseous. i have a fear of throwing up and also of nausea. the ER (for my kidney stones) gave me a huge jug of Gavilyte. no thank you!! but im so backed up that they couldnt even read my abdominal xray to see the stones lol…

basically i want something STRONG that wont make me sweat shake and feel sick. ive done every laxative pretty much. worst experience was an enema. cried because i felt so ill. also was very sick off dulcolax back when i was like… 14 and never took it again. if i get nauseous from laxative, ill take a zofran, which will just overpower whatever laxative i take. any advice or help!!?!

doctors typically recommend me

milk of magnesia, miralax, and metamucil.
