Hey there Jake. I started HCL today. I took just one tablet on an empty stomach to guage my bodies response to it. However, I am not really sure what I should be looking for as I have never experienced heartburn before. Tomorrow I plan to go to 2, and the next day 3. I am doing this as per your suggestion to see if I get a reaction to it before going into it full on. Can you please advise what I should be looking for in terms of a reaction? Maybe it might be blatantly obvious when it comes but so far I have experienced nothing of note. One point before I go, there is one particular thing I have done that can make me feel extremely well for a short time. This is to take a massive dosage of probiotics (ie; 10spns of Acidophillus at once etc). Just thinking, I wonder if its something to do with 'acid'. That being the case, it might be a good indicator that this could work for me.
