So I've been working out for about 6 years, and probably drinking various protein shakes for about the last 5 years, rarely more than 1 a day though, sometimes two. I've been having this issue probably at least the past couple years, maybe longer, but I'm not sure since I never really started pinning it on the protein drinks till recently. Never wanted to pin it on them since I consider them healthy and without them I'd never get adequate protein.
But heres the deal, I usually drink optimum whey, sometimes syntha 6, sometimes muscle milk. And I've noticed it seems like 90% of the time I drink a protein shake, without eating a large amount of food, I end up feeling real sh*tty. The most dramatic example is when I drink a protein shake in the evening, either right before bed or sometimes a couple hours before bed, it seems like 9 out of 10 times I wake up with a very bad headache that is extremely difficult to get rid of, as well as a bit of nausia, etc. It just ruins my day. Its happened today, and I've taken ibuprofen, tylenol, caffeine, ginko biloba, and although its better than when I woke up, I still have a headache and feel pretty sh*tty, and its 1:35pm. Its my day off, and its half wasted because I literally haven't done anything except sit around feeling bad, taking headache medicine's etc. to try and feel better.
I always thought it must be something else wrong with me, however I'm very healthy, only 27, and the days this happens are always after drinking a protein shake the night before. And by the way, no I'm not lactose intolerant, I can eat all kinds of dairy. And it seems to happen with any brand, not sure if its the artaficial sweeteners or what.
Now another example is during the day, occasionally if I feel I haven't had enough protein in the morning or afternoon or something I'll drink a protein shake, usually along with a small snack like a couple slices of wheat bread or some nuts or something. You'd think it would be a healthy combo, however usually I feel pretty sh*tty after a couple of hours. Not as bad as when I go to bed after drinking one, but nevertheless pretty bad.
The one time it doesn't seem to happen is if I eat a very large amount of food after drinking one. Like say I know i'm going to eat a pretty big amount of something like mashed potatoes, or spaghetti, or something else that doesn't have alot of protein, I can drink a protein shake beforehand, and as long as I eat a large amount of food, I usually feel fine. I just can't always have the time to eat a large amount of food afterwards, especially if its after my evening workout before bed.
I'm just wondering does anyone else have this problem? Does anyone have a solution? I want to keep drinking protein drinks since I know they are beneficial to my muscles, but i'm sick and tired of how much time is spent feeling sh*tty.
