Took my first stick last night. Basically I reconstituted 5mg DAC with 1/2 ML water (smaller slin pins). Figured I would start with 1/4 of that, in essence 1.25 mg. Pinned it last night. Didn't feel a head rush or get really tired. Got a little hot though about 5 minutes after taking the stick. my face and arms all got kind of hot. Is that normal? Seems like I can probably handle. 2.5mg at once. I just wanted to test it out first.
