YES! I had those issues ... but here is something that I found and loved... they should pay me as much as I post on them but Cytosport's ready to drink (RTD) "whey isolate" Protein drinks... they are in 16 oz bottles and have 32 g of whey protein. I LOVE them - tropical and tangerine flavors (I don't personally like the watermelon). I buy them at Vitamin Shoppe for 3.79 a bottle.
Also many folks like Isopure RTD bottles, but I did NOT. Those are 4.19 a bottle.
Also fyi, I love Vitamin Shoppe! One reason: they will take them back if they are opened w/in 7 days w/your receipt. They can be bought (both of the kinds mentioned) in their refrigerated section.
Additionally, the powerpak protein is good in chocolate. Those I think are $3 and some change for each.
For Butterbean's comment: My dr. suggested taking mirolax whenever I don't go on my own every 2-3 days, as well as acidophilous pearls, which are a priobiotic that helps keep things moving, from my understanding. I also eat a prune or two every couple of days. Hey it helps get that sweet craving out for only 15 cals per prune!
And definitely get that Water in. I hate water, but like the fruit20 (peach is my fav) and propel (in berry usually) or crystal light in cherry pom... if anyone can use those tips that is!
