Confused about dosage and amount
So my doctor told me to start out at 2.5 mg, but I don't think that'll be enough. The doctor said that there is 50 units in the vile which should be 5 mg if I'm mathing right. Should I just take the whole thing? Based on my 2 seconds of research, I'm worried 2.5 mg won't be effective. I definitely know more than my doctor so it's not even worth asking. Also I'm worried about cost, so taking 5 mg should save me a good bit of money right?
After the 5 mg should I also take reta? and how do I take that? It came in a white powder. I think I'm supposed to snort it.
