Is it strange to get shaky hands after not taking your daily allergy medicine a few times?

Interesting question: Initially i thought not, but some allergy medications have decongestants which have anticholinergic effects. Anticholinergic medications can help some tremors associated with parkinsons. I wonder if not taking causes a withdrawal tremor or if you have been taking many years, is there a family history of tremor that has been masked by the medication? Consult your md.
