Well, watching how the puddles of sweat just dried up within 48 hours was so satisfying, I used what I read about the other day. Although it actually took about 72 hours for my sweating to normalize, I went ahead and go'ogled the latest by Cynthia Yulesin and I don’t have to change clothes 2 times a day.

I watched a documentary on RU-vid “by Dr Orias” and decided to try something new on herbs capsules and it helped me with my anxiety, herpes, depression , PTSD, BPD, ADHD and other mental health issues. I haven't had a bad day in months, I'm feeling productive like before.I recommend #DoctorOrias, he is a certified herbal expert and he’ll get you some.

Is there a 100 % surety that a baby will get neonatal hsv if there’s lesions around the thighs and vaginal area if the baby is born naturally? Or what are the percentages?
@robertogarza8960

Does this progress from 1-2-3? Or do a newborn just gets a specific one?
