Anyone else experience this for no known reason?

Good morning OH friends.Ok,I have been having upset stomach since Friday along with tiredness & weekness.It started while I was shopping at Walmart Friday morning with my brother.First I thought it was something I ate but it`s still happening.Could lack of protein cause all of these symptoms?I have been using Body Fortress protein shakes from Walmart in Chocolate & vanilla.The shakes taste really good.Or at least they did.My stomach suddenly started rolling over at even the thought of those shakes or of having to take all these vitamins along with my usual morning pills.It got so bad Saturday I couldn`t even take a sip of water without wanting to throw up.It gets better then gets worse again.This goes on allll day!Now this morning I find myself very close to throwing up after taking my pills with 1% milk.The thought of the milk makes my stomach churn.I love milk!And I had no problems what so ever with the 1%.Now I can`t stomach it.I`m thinking I may have to go back to 2% but I don`t want the extra fat & calories.I have had aprox.1 maybe 2 shakes total since at least Thursday.Do your taste buds change anytime after surgery?I`m almost 2 months out from mine.Have been on solid food ever since day 5 with no problems what so ever.I`m tired of this queezy stomac.It feels like all day morning sickness & I know there`s no way I am pregnant cause that  dog don`t hunt anymore.So far I`ve been able to fight off actualy throwing up because I would rather have all my teeth pulled out at once again than to have an upset stomach so when I get the urge to throw up I fight it like the plague!Is there anything that will help?

Check with your doctor and see if it might be that you have become lactose intolerant. It happens to some RNY patients.

Is it just the milk bothering you? There has been a stomach bug going around here lately, maybe you just came down with something?

When I got to that point with my shakes, I switched to soy milk and it solved my problems.  I guess I became lactose intolerant.  You may want to give soy milk a shot. 

It`s not just with the milk.So far,the only thing I`ve been able to eat without getting super queezy is oatmeal & watermelon.Anything else makes me sick.It doesn`t matter what it is,meats,vegies,I get to a point where I feel better but it`s not long before I`m queezy again.I felt ok when I got up this morning untill I had to take my vitamins & other pills.The milk had a kindof sweet taste,like it was about to start turning.But I just bought it & I know it`s not bad.I guess I`m just gona have to go back to liquids only for a few days & if it still doesn`t get any better contact Dr.Ayloo`s office.I have been tired & sick to my stomach non stop all day today.Oh I forgot,Saturday I also kept getting dizzy with this.
Thanks for all your suggestions

I am 6 months out and my tastes seem to keep changing. I could not do shakes unless I had milk before surgery and since surgery I only use soy milk. And now I am noticing all of sudden I don't like water with my shakes. So I totally understand.

Wow!Well I was doing good on the 1% milk but all of a sudden it tastes nasty & makes me sick to even think about it.But I drank some of my husbands whole milk & it didn`t bother me.So I think I`ll go back to my 2%.I`ve just been having a lot of gas,bloating,teeny bit of acid reflux,upset stomach.I`m thinking now maybe I`m eating too frequently,I know I`m not getting enough protein & fiber.Anyway I go to the Dr.Tuesday so I`ll know more then.
Thanks for all the replies.
