Last cycle i did was about 2years ago and as I started getting bigger and bigger the heartburn got outta control. Many nights i'd wake up coughing and get a nice splash of stomach acid i'd puke up. Only really happens in mid night. So I went to dr and he just recommened I take prilosec but I requested an endoscopy to see if any damage occured and I was fine. They took some biopsys and all was good. So after I dropped from around 260 down to about 245 the problem went way. Well I recently started a cycle again and im around 255 lbs right now. Much leaner than years ago and my diet is also much better(before I was mass calorie fast food,etc..) Im noticing the same thing is happening again though. I started some priolsec to see if it goes away, but im wondering if anyone else gets bad heartburn and burps up acid on cycle and when they go up alot in weight.
