I got my Huel last night, and I was anxious to try the very next day. So, I had a shake for Breakfast and I felt good, no sudden runs to the bathroom and what not, just felt good over all. For lunch, I was very hungry and had a Turkey burger with french fries and slice of pizza ( yes, a bit much, but it was good). Then 3 hours later, I was getting very sleepy ( digestion, I suppose…big lunch after all). So, I decided to have another shake, well it the job, that is woke me up, but then I started to feel bloated at first, then like I was going to pass out, heart attack, etc. I m not sure why, perhaps not enough food ( I normally have breakfast, lunch and dinner, totaling about 3000 calories more or less).
