I think I may be noticing that caffeine is actually interfering with my medication (Dexedrine). Before I was diagnosed I used to use exclusively caffeine to try to concentrate at work. Usually Coke, but sometimes coffee as well.
In the last few weeks I've noticed my medication hasn't been working as effectively as it was at the beginning. Today I had a Coke in the morning, but not in the afternoon, and suddenly I'm feeling the effects of the medication I took this morning. I'm thinking it might be because the morning Coke has worn off.
This might explain the last few weeks, since I've been using caffeine more often recently. Does anyone know of this kind of interaction?
The difference is that the caffeine seems to block the euphoric effect of the medication. It makes me feel 'cold' instead of 'warm'. Jittery and anxious. That used to be the only way I could get work done. But now I wonder if it's actually blocking the beneficial effects of the medication. Does this make sense to anyone else? I hope it's not just my imagination.
