Empowerment
Sending you lots of support. I've not taken praziquantel before, but I talked to someone on here a few days ago, he/she took a horse drench containing prazi and ivermectin, several nights in a row. He felt like crap, too. REally unwell for about a week. He took a strong laxative (NuLax fig/date/senna) each night before bedtime, to clear out the crap first thing next morning.
He took lemon, also, lots of lemon, to help the liver. The liver apparently gets overloaded, trying to clear the parasites.
But - I don't know if it's acceptable to vomit after taking prazquantel. It might be an adverse reaction. Do not take any more of it at this stage. Let this dose clear out of your body for a few days.
How much did you take? In what form? What do you weigh?
I don't know what those things are, in your photos, but if you feel better after getting rid of them, then that is great.

Hang in there. You will get better :)
