Last night I was out drinking. The 3 drinks I had were strong, I got a headache not long after. Around 3am I was in bed trying to fall sleep and took 150mg of Seroquel to fall asleep. This morning I drank my usual cup of coffee. I think the combination of these 3 was not a good idea because I've had chest pain since this morning. It's just on my left side but it worries me because I had open heart surgery. I'm taking it easy and hoping it's just a matter of time before the pain goes away. It has lessen in the last hour..but yeah I see now it wasn't a good combination.
