Question: Previously had 3-5 fainting spells. Time period maybe 4-7 years ago. However, recently and very suddenly recently I have these waves of feeling very unwell. Febrile where I have these cold shakes that are like mini seizures. I have fainted once. I did some digging and as a former combat medic this my understanding: **But I saw a lot of alarming stuff about Stacker & Dr. Stephanie's products. Should I discontinue to products immediately and see if the improves it?** If not, refer to ED correct? Any other insights as to what is going on. These random waves of static Febrile that just as suddenly leaves is odd. Also, could the stress be doing this? Any insight would be most Appreciated.
