18 years ago, I had an anaphylactic reaction after taking Bayer aspirin. Dr said never take aspirin again! I haven't. Do you agree?

Yes. Anaphylaxis is a life threatening reaction. If you have had that reaction to Aspirin in the past, a rechallenge with the same medication is unwise. If there were no alternative, then it may be reasonable to attempt a desensitization process., but that is not the case here.
