Ok let me lay out the background for you. I started taking DS Lean Xtreme and PES Alpha-T2 last Wednesday. I have been dosing 1 of each upon waking up and then 1 of each again pre-workout at around 5pm. Never noticed any side effects. Fast forward to this morning. I decided to bump it up to 2 Alpha-T2 and 1 LX upon waking. I also had 100mg of caffeine that I usually do not have in the mornings b/c I have been extremely tired at work in the mornings. I think this is due to being on a CKD diet and possibly lack of long sleep also. After getting to work I had a feeling of nauseousness for about 15-20min, but it went away and I felt fine afterwards. About 15min. ago I suddenly felt my heart pounding in my chest very hard. It couldn't have lasted more than 10-15 seconds and from what I could tell it was not going any faster or slower than normal while resting, just beating really hard. It feels ok now except for the fact I am aware it happened and now it's kinda freaking me out. Paranoid much? Anyways I just wanted to know if anyone else has experienced this or has any ideas / suggestions for me. I have read that caffeine and thyroid issues can cause heart palpitations and also Alpha-T2 seems to be regarded as a stim in some threads, yet at the same time I read that I shouldn't experience stim like effects for the most part due to its specific make up. Thanks for your help. Also if this is not the right place for this post I apologize.
