I just had a nurse tell me that many of my problems could be related to beer. I am on an anti-depressant Effexor but have always been fatigued and seem to have all the symptoms of chronic fatigue syndrome. I do often have 2-4 beers in the evening. I did notice I am less likely to have muscle and joint aches in the night if I don't drink. However, for example, today I just can't seem to wake up. I am not a coffee drinker and I did have 2 beer around bed time. Could that cause dehydration to the point that in the morning it is hard to function? I seem to tolerate alcohol well but am wondering if it contributes to my problems? Any ideas?
