Are CoQ10 And Fish Oil Effective Alternatives To Atenolol?

Good morning! I have considered getting off of my HBP medication Atenolol and resort to a more herbal remedy as in supplements(capsules,powders) or teas. I have been reading the articles on here regarding uses, side effects/interactions. Would a CoQ10 and Fish oil combination work just as well? My Atenolol is only 25 mg and i have been on it for going on 13 years. They were not able to prescribe me my meds due to reason of missing ingredient in the batch they just made . hmmm. So i was wondering if i could substitute with either the CoQ10/ Fish oil or if you would recommend a somewhat small dose of possibly Hawthorn? I would prefer to not be put on something else for the time being , or until next months batch . I will hopefully be speaking with my g.p. this morning but i took my last pill last night as i was informed that i could not refill my scripts. so hoping there is not an all day excursion of phone tag and if so i would like to resort to something more natural if possible. and something that i could also speak with my doctor about if i get a chance today, before it s too late. Thank you.
