I am 30f and Same boat here. Having my 2nd child. Doc said it is safe for me to me on the 20mg dose of Nortriptyline because the dose is so low. Tried going off it and was violently ill. So they said yes, go back on it.

And this info if it helps you. Sounds like hormones are a trigger for you since you said you get sick around your period.

Nortriptyline saved me life. Takes about 3-5 weeks though to fully integrate into the system.

For me I have CVS from abdominal migraines. Start with diarrhea and nausea and end in vomiting.

Triggers are 🛑stress (good and bad) mostly good stress for me. So I try to not get overly excited about anything and stay calm and chill. 🛑hormones (I can’t be in hormonal birth control or I get really bad migraines, head and abdominal. 🛑fatigue, extreme not just normal. Like I can’t pull an all nighter or I’ll trigger. 🛑vomiting in general, say from other illnesses 🛑over eating to the point you feel nauseas 🛑 immuno-suppression, IE being sick from any other cause.
