4 months and tired

So I started because I got injured almost two years ago lifting and my A1C shot through the roof since I wasn't adjusting my diet to accommodate my lack of exercise. I started in October and have had great success but honestly the side effects are making it feel like it's not worth it anymore. Spending wed-fri throwing up and stuck to the toilet is wearing me down.

Does it get better eventually or is it just something I need to suck up?
