Not the usual ones of dizziness, rapid heart rate, and palpitations. I experienced fatigue and insomnia but the worst side effect was terrible constipation and bloating, to the point that even taking laxatives (Miralax) and stool softeners did not alleviate it.

It was so bad that it was distracting me from work and reducing my energy levels and willingness to exercise. I tried three times to make it work and made sure I was very well hydrated while I was on it.

My belly increased three inches in size due to the bloating.

I also had joint pain on round 2. Round 3 wasn't as bad but the side effect mentioned above was enough to get me to stop it again.
