I went through HELL for 2 weeks (nausea, severe irritability, anxiety, hot flahes, cold chills, fever, sweaty palms, back pain, insomnia, and absolutely no energy) before anything started to ease
up. I was in the ER because the symptoms
were unbearable. I've been to
the doctor twice and urgent care once for symptoms and because I was sick with a cold.
When going through withdrawal your immune system is weak, therefore it is much easier to become sick.
