I had been taking Claritin and it's pretty weak so I switched to Zyrtec and it seems to work much better but messes with my sleep. It's like I can't get out of bed the next day. Maybe that side will disappear after a couple weeks. I've started to notice the list of side effects on most drugs is nearly useless, they never quantify anything. Any opinions or anything that should be noted about bodybuilding and allergy meds?
