Fiddle, hand doesn't look like phlebitis at all.
In the past couple of weeks you have been listing a variety of symptoms that you are having. Now knowing that you have been taking thermogenics it all makes sense. (Excess sweating, increased heart rate, palpitations/throbbing) I think it's great that you are stopping the supplements. To me, it's one thing to add Protein or even BCAAs after a workout but not much else beyond that. Whenever you get to competition, would you rather look back and be proud of what you accomplished on your own or to know that you accomplished that with supplements? Stay with your "all natural" thinking, it's doing good for you. Just my opinion.
