I started using Beta Alanine 800mg 4 times a day as per instructions on the bottle. Even on the 1st day I noticed a huge pump difference durring my workout, but I noticed that I was having trouble with my breathing. I could breath, but it felt like I needed to take a deep breath but couldn't. I have also had this side effect with L. Arginine. I stopped taking it after 2 days as it seemed to get worse. After a couple days off of the Beta my breathing returned to normal. Has anybody else had this same side effect or know why this is happening. Thanks all...
