I decided to start a trial of thyroid hormones, and took one grain of Thyroid-S for three days. On the third day, I also added 20,000 iu of vitamin d3, thinking it would help things.

Well, I got a strange reaction the next day when I took my other usual supplements, along with more vitamin d3.

After taking a simple b12 tablet, which usually has no instantly noticeable effect on me, my head was spinning all day. In an attempt to get to sleep at night, I took a capsule of 5-htp, and the effect was insane….I had awful brain fog, yet I felt fantastic, as if I were on drugs.

What the vitamin d3 must have done is amplify the effects of anything I put in my body by about 100 times. A few days later I had a beer and minutes later felt extremely drunk.

Needless to say I have stopped taking vitamin d3. Is this sort of reaction common, or does anyone know the mechanism which it could have done this
