Protein giving a "high" feeling???

Ok, have a been off so long that I don't remember this...I've been trying to do more protein shakes and noticed when I drink them a get a lil bit of a high/dizzy feeling... is it cuz of the amount of protein at once?  Gosh how far we slip when we don't keep it up...  they are low carb/cal/sugar so it's not that... I do a scoop and a half at once so I get 30 grams at protein at once...which is what I've always done..mixed w/ water... so there is no change in how I've done it's...it's just been a while.   Update from last week..I did ok for a few days then messed up again...so I lost a few and gained a few but the good news is I didn't go weeks in between so that's a start.

Kellie, I suspect you are experiencing more of a carb withdrawal then a high from the protein.  At least I get it when I really cut out the carbs...I'm not a nutritionist however.  I do know that the body works harder to process protein, so maybe the blood is leaving your brain to go work...who knows???
