Weaning off Restavit after pregnancy

I’m currently 25 weeks pregnant and have been taking 6.25 mg of Restavit (doxylamine succinate) almost every night since around 15 weeks. I tried stopping a couple of times, but the insomnia and nausea came back, so I ended up starting it again.

I’ve read that plenty of people take it throughout their entire pregnancy, but I’m wondering what happened after birth. Did anyone stop it cold turkey once the baby was born? If so, did you have any issues?

I’m also wondering whether I should start tapering off now while I still have about 14 weeks to go, or if I’m overthinking it 😅
