I been struggling to get my protien this week..I'm too full on liquids and/or just can't stand the thought of another nasty shake...now I'm sure as a result I've been a little light headed here and there..well I just had a brilliant idea to mix a spoonful of peanut butter into my shaker with my protien powder etc....it completely dissolved into the drink and it was delicious..added another 8g of protien...and almost immediately I feel human..was that bad?

I don't think so at all. I supplemented with Peanut Butter at that time too. Above all, listen to your body- it will tell you what you need! When in doubt- call your doc or nutritionist.
