Ever since I started taking 300-400mg of Wellbutrin (Bupropion) per day, I noticed that I would get very tired after eating protein. Especially large amounts of protein--when I would have my whey protein shake (containing ~18g protein), I would get *super* tired for about 20 minutes starting about 5-10 minutes after eating it, and stay noticable tired for up to 40 minutes.

It's not like I get very tired after eating a normal meal that has some protein in it. Just when I have a lot of protein. I haven't yet figured out if it matters if I have *just* protein, or whether I would still get tired if I had a lot of protein along with carbs and fat.

Anyone else notice anything similar?
