I am on levithroid. 120mcg..after approx. 1.5-2 hrs, i follow up with a fat burner called oxyelite pro. Ive taken this before and experienced no side effects other than the the normal jittery and elated phase. I quit using the fat burner and started again 3 months ago..1 cap in the morning and another in the afternoon. However, this time, the experience is different. there were times ive had abdominal pain immediately after taking it. other times, i feel light headed and i've also experienced chest pains.
I am 5'7, 140lbs. my last lab work came out normal. as of this writing, i am experiencing headache, not uncomfortable headache but I can feel pressure in my T-zone.
