I am on my 4th day of taking it and the first 3 days I only did one dose of 25mg E and 200mg C. Today I added another dose (2nd dose) of the same (25mg E and 200mg C). I am noticing things I didn't notice before like having trouble swallowing, indigestion, and almost like a dry heave feeling. Not so much like throwing up, but kinda like a dry heave/gagging feeling. I thought maybe I was just dehydrated from the caffeine, but I have been drinking tons of water. Anyone else get this type of thing when on it. I certainly do not enjoy it and I am considering getting off the stack. I don't know if it is a direct side effect, or more so from the decreased carbs and cals in my diet since being on it.
