Feel like I have the flu and terrible heartburn

I was doing fine on my cycle until I started with insulin. I started with low doses and worked my way up to 15iu's PWO. Anyway, I feel like crap whenever I take slin even though I have more than 150 grams of fructose/dextrose right after taking it as well as high sugar intake the rest of the day. Low energy levels, tired easily, heavy breathing.

To top it off, I have had really bad heartburn.

My gains are good, but feeling like this sucks. Stopping the slin today. I am almost sure it is not test flu as I have never had these problems before, and i still convert the very same way as before under clean conditions.

Any suggestions?

bro if you feel that bad stop asap it not worth it!
