2 Months Ago, After Enduring 7 Months Of Pain An

2 months ago, after enduring 7 months of pain an sleeplessness after an auto acident, I started drinking wine and beer for the first time to help me sleep and relieve pain without a pill. Since so doing, I've gotten pneumonia & bronchitis for the first time ever. I relate this to the drinking of alcohol because of the timing and I dropped the alcohol. Are there any scientific medical studies relating the two? I wonder?
