Hello Doctor,
I was diagnosed with Generalized Anxiety Disorder and my GP put me on Wellbutrin XL 150mg. I went back to him at the beginning of January and he upped the
dosage to 300mg. Since I had just filled my prescription for 150, he told me to take 2 until they were finished. I didn't have a problem until I got the 300mg pill (January 20). I usually take the pill with food, but it seems that by 1-3pm, I start to get weak and nauseated.
