My Medicinal Dilemma

So the cold has developed now into a full blown illness and I feel like crap.
In order to reduce the misery somewhat, I've been taking Lemsip Max Cold & Flu capsules, and this has been easing the misery of the blocked nose, headache, etc.  However they seem to be having a very negative effect on my stomach meaning I feel sick almost all of the time after taking them.

So I have to decide..
Do I want to feel crap because of the cold or because of the cure?

Surely there's another way?
