I have been drinking Boost for a little over a month now ever since my grandpa persuaded me to try it when I had an upset stomach one day and couldn't manage to choke down any real food. I think I had eaten some bad food one night, vomited and vomited and felt horrible afterwards. Nothing appealed to me after that but I knew I needed to eat and drink the next day to keep my electrolytes stable. My grandpa swears by his Boost High Protein drink so I decided to humor him and give it a try. To my surprise, it was at least somewhat palatable and did give me an almost instant "boost" of energy. Luckily Boost does not contain caffeine or any other crazy stimulant ingredients, just vitamins, minerals and protein. It is, however, derived from milk protein so be careful if you're lactose intolerant.
I don't normally take any vitamins or special supplements but I try to be somewhat conscious of what I eat on a daily basis. That is, I pay attention to the important stuff like getting plenty of salt, potassium and fluid intake. I definitely wouldn't say I eat a perfect diet though. I still eat junky processed foods when I have a craving, but overall I try to get a good variety of different foods in so didn't think my body was really lacking anything in particular. Perhaps that's why I was really surprised by the way my body reacted to Boost. After a few days of drinking it, my resting heart rate was totally normal (60's sitting!) and only jumped to the 90's when I stood up. I realize that that jump still meets the criteria for POTS, however, it is much better than my usual jump into the 120's. I have been drinking one a day religiously for the past month and I am pleased to report that my numbers have been looking much, much better. I don't know why, maybe my body was lacking some essential nutrient contained in Boost, or maybe its pure coincidence and my POTS is finally cooperating for once, but I really have been feeling better most days. I hope this trend continues. I am definitely going to keep drinking Boost, it couldn't hurt. My gut instinct says it is at least partially responsible for the recent improvement in my numbers and how I feel.
