Erythromycin and stomach

My stomach feels a little upset and some diarrhea...never felt down or depressed. Works great for me.

I am actually very relieved and excited to see that there is a connection between erythromycin and depression. I had taken erythromycin for years for acne. I found a strange correlation between taking the drug and feeling depressed. I asked both my doctor and pharmacist about this, and they both responded as if I were both crazy and stupid. "Of course not," was the reply. So I continued to take it.
I began taking it again about a week ago, and have found that I've been slipping into a very dark depressive state. This time I am very aware of what is going on around me, since I stopped taking my anti-depression medication last February (under the care of a physician and a psychiatrist) I am noting the same 'darkness' that I felt in previous times with erythromycin. A general 'nothing matters, might as well die' sort of attitude, as well as irritability and a strong desire to isolate. I started researching this morning on the internet, and I have found several links now. There have been studies that have shown a direct correlation between erythromycin use and depression.
Okay, now, here's the kicker: the erythromycin I've been taking is topical. It's a 2% solution, suspended in alcohol. I've been slathering it on my face three or four times a day. Apparently it doesn't matter if it is absorbed through the skin or through the stomach/intestines. Erythromycin causes depression in me. I don't care what my face looks like. I'm going to stop taking it.
