Do you have allergies to these medicines or just
adverse effects? Allergies are a biochemical response to chemicals that cause measurable physiologic changes and can be lethal. What many people call allergies are actually just adverse effects of the drugs (e.g., upset stomach from aspirin). Adverse reactions can be tolerated, allergies are more complex.
Have you talked with your doctor? For example, Atenolol can definitely make people feel tired and foggy.
