Hi, I went to my chemist today to get some Flaxseed Oil (Nature's Way) to help with bowel movements (not happening, am currently on Induction). Funny thing I took the first two capsules after lunchtime and I have had a constant headache ever since (luchtime being 2 hours a go). Anybody experience headaches when they first starting taking them? or any other side effects for that matter? I also purchased some GNC Psyllium capsules (500gm) I have taken one and nothing has happened.....should I take two? I thought it would be safer to wait until bedtime and take the two but then again I need to go!! How soon does it start working? Silly questions but an answer will be appreciated.
